Documentation to be completed/added post-Beta

This chapter introduces the Insight application, describes the Insight project, describes interface features, and explains how to select visualizations.


What is Insight
What Is Insight?

Insight is an application for analyzing, visualizing, and conditioning data. With Insight you can have the advantages of IDL's computing environment - powerful, array-oriented language, mathematical analysis and graphical display techniques - without having to know the IDL language. You can use the Insight interface to analyze, visualize, condition, import, export, and generate data. You can view and modify visualizations in the Visualization window and data items in the Data Manager window. The best way to discover Insight's many features is simply to use the application. An online help system is available to guide you through Insight operations.


What is an Insight Project
What Is An Insight Project?

A project is a group of related components which are used together. A single Insight project contains various types of information (data and windows), including:

•	The configuration of a visualization window

•	a data area (with items listed in the configuration of a Data Manager window)

•	style lists

•	color tables

You manage, save, and store multiple Insight components together as a project. The project file has an ".ipj" extension. Files within a single project share information.   You can create, open, and save multiple Insight projects during a session. Insight projects cannot share information with other projects. See Also:

"Visualizing Data" on page 33

"Working With Data" on page 21


The Insight Interface: Introduction

Insight's Visualization window is the hub from which you navigate to other areas of your Insight project.

Scrolling In The Window

Scrolling Bars are the shaded bars along the right and bottom sides of a window or scrolling list. The position of the scroll box in the scrolling bar indicates the part of the window or list currently displayed in the window. To scroll quickly to another part of the window or list, drag the scroll box. To scroll in a given direction, click the arrow at that end of the scroll bar while holding down the mouse button. Release when you reach the desired location.

Selecting Menu Options

Insight groups options, or commands, on menus. Some options perform an operation immediately and others open dialogs so you can select more options. To select an option from a menu, use the mouse to point to the menu name on the menu bar, click the desired option, and release the mouse button.


The Insight Interface: Working With Dialogs

The Insight application sometimes needs additional information before it can perform an operation. In these cases, selecting a menu option opens a dialog in which you can select options. Actions you'll perform in a dialog include selecting on/off boxes, selecting items in droplists, and typing or editing text in text fields.

Note	The difference between a window and a dialog: A window provides a viewing area or workspace and contains a menu bar. A dialog prompts you for additional information.

Insight sometimes allows you to move easily between the current window and an open dialog. At other times, you must close the open dialog before you can continue working in a window. This manual specifies the requirements of each dialog.

Note	The figures in this manual depict MOTIF, Windows, and Macintosh windows and dialogs. The dialogs and windows for all three systems operate in a similar fashion. For more detail on using windows and dialogs for your operating system, see your system user's manual.

Moving Within Dialogs

Within dialogs, move from one text field to the next using the tab key or by using the mouse to click in each text field.

Selecting Options In Droplists

To select options in droplists, use the mouse to point in the droplist rectangle, click and hold down the mouse button, drag to the desired option, and release the mouse button.


The Insight Interface: Standard Insight Dialog Buttons

This section describes the buttons that most frequently appear on Insight dialogs. Select buttons by clicking them.

OK

Clicking "OK" permanently carries out an action(s) or saves modifications specified in the dialog and closes the dialog. In Analyze dialogs, clicking "OK" also generates and stores a new item which is listed in the Data Manager window.

Help

Clicking "Help" opens Insight's Online Help system to get information on the dialog and its components. The "See Also" sections in the online documentation also contain topics that you can click for additional information.

Apply

The Apply button appears on Analyze dialogs. Clicking "Apply" carries out an action on a "trial" basis. This option is helpful when you want to "try out" various options before generating a data item to be stored and listed in the Data Manager window.   You can click "Apply" as many times as you wish. When you're ready to generate a new data item, click "OK."

Cancel

Clicking "Cancel" cancels any modifications you've entered and closes the dialog.

More

Clicking "More" expands the dialog, providing additional dialog options.

Less

Clicking "Less" closes the additional section of the dialog that appeared when you clicked "More."

Note	Since on/off buttons look different on each operating system (Windows, Macintosh, Unix), your buttons may not look like the examples shown in this manual. However, the way that buttons work on any system is the same: you select the option a button represents by simply clicking it.

Entering Paths

Selecting or saving files often requires entering paths in a dialog's text field. Each platform (Windows, Macintosh, Unix) requires paths to be entered in a different way. For more detail on how to enter paths on your operating system, see your system user's manual.


Moving  Visualizations and Elements
The Insight Interface: Moving Visualizations and Elements

You can move visualizations, images, and axes in the Visualization window in two ways:

•	Using the mouse, click on a visualization, image, or axis. Holding down the mouse, drag the element to the desired location, and release the mouse.

•	Using the mouse, click on a visualization, image, or axis and select the Properties option of the Edit menu (or simply double-click the visualization, image, or axis). A dialog opens which allows you to enter a new location. For more information on changing properties, see "Dialog for General Visualization Properties" on page 48, "Properties Dialog for Images" on page 56, or "Properties Dialog for X and Y Axes" on page 59.

Note	Make sure you click on the desired axis or entire visualization itself and not one of its elements. To select a visualization, click its title or within its bounding box. (Direct Manipulation of other graphic elements is to be added in Insight Release 1.0)

Scaling Visualizations

To scale a visualization to a percentage of its current size, use the visualization's scaling handles. Scaling handles are located in the four corners of the visualization's bounding box (visible when you click within the visualization's bounding box). Simply click a handle, hold down the mouse, drag until you reach the desired size, and release the mouse. (The visualization remains selected.)

Rotating Surfaces

You can rotate surfaces in two ways:

•	Using the mouse, click on the surface. Holding down the mouse, drag across the surface in the desired direction of rotation. When you reach the desired angle of rotation, release the mouse.

Hint	This works best with solid surfaces. (If you rotate on other surfaces, such as wire mesh, you could click on a non-surface section of the visualization and drag the entire visualization instead of rotating.)

•	Using the mouse, click on the surface and select the Properties option of the Edit menu (or simply double-click the surface). A dialog opens which allows you to enter the angle of rotation. For more information see "Properties Dialog for Surfaces" on page 57.

Working With Data

Documentation to be completed/added post-Beta

This chapter introduces Insight's Data Manager window and menu options; describes data attributes; and explains how to access data associated with the current Insight project. You will learn how to use the Data Manager window's File, Edit, Condition, View, and Utilities menus to work with data.


The Data Manager Window

The Data Manager window is your view of the Insight data area associated with the Insight project. Basically, it's a list of the data files together with information about them. To open the Data Manager window, select "Data Manager" from the File Menu in the Visualization window. The Data Manager window opens with a table listing the attributes of data files which have been imported or created for the current Project. Insight lists data items in rows with attributes displayed to the right of each.


The Data Manager Menu
The Data Manager Window Menu Bar

The menu bar across the top of the Data Manager window groups options for manipulating Insight data items into six main menus: File, Edit, View, Condition, Utilities, and Help. When you select a menu option that is followed by an ellipsis (...), Insight opens a dialog or window so you can enter more information or select options before performing an operation. The operations you can perform include:

•	customizing your view of data items and their attributes

•	creating and importing new data items

•	conditioning existing data items

•	selecting and modifying attributes of existing data items

•	changing scalar or array values of data items

This chapter describes all of the Data Manager window's menu and dialog options. For help using a specific menu option, you can navigate through this chapter or jump to a specific topic by selecting from the choices below:

Importing and Exporting Data: The Data Manager File Menu

Editing Visualizations: The Edit Menu

Viewing Data: The Data Manager View Menu

Conditioning Data: The Data Manager Condition Menu

The Data Manager Utilities Menu

Data Manager Help Menu


Data Attributes Overview

Insight organizes the information describing each data item as a set of attributes. Attributes include name, classification, type, dimensions, element, description, scalar value, lock status, minimum value, and maximum value. This section describes these attributes.

Note	To modify one or more attributes of a selected data item, select "Attributes" from the Edit menu in the Data Manager window. To modify an array value of a selected data item, select "Value" from the Edit menu of the Data Manager window.

An imported data item will retain its attributes. When you create a new data item in Insight, you assign the attributes. For example, when you select "Create Data" from the Edit menu in the Data Manager window, a dialog opens which allows you to specify attributes for your data item. See "Data Manager Create Data Menu Option" on page 26. You also assign attributes when generating new data using Analyze menu options in the Visualization window. See "What is Data Analysis in Insight?" on page 61 or "The Analyze Menu" on page 62.


Data Attribute Types

This section describes the types of attributes associated with data items.

Name

This field displays the name of the data item. Each data item created in Insight has a name assigned by you or Insight. Names must start with a letter but can include letters, digits, underscore characters, or dollar signs. A name can have as many as 255 characters.

•	Imported data items retain their original names. For example, when you view an imported data item in the Data Manager window, you will notice that its "name" attribute matches its original filename.

•	Data items generated using Analyze dialogs are listed by the name you specified in the dialog's "Outputs" text field or by an Insight-assigned name listed in that text field. For more detail on the "Outputs" text field, see "Outputs Text Field" on page 66. For general information on generating data using Analyze menu options and dialogs, see "The Analyze Menu" on page 62. Naming scheme: post-Beta documentation

•	A data item generated using the "Create Data" option from the Edit menu in the Data Manager window is listed either by the name you specified in the dialog's "Name" text field or a name assigned by Insight. Naming scheme: post-Beta documentation

Classification

This field displays the classification of the data item. Insight classifies each data item as one of five types of variables: Array, Vector, Two-Dimensional Array, Image, or Scalar. A variable is a named repository that contains data with type and structure.

Type

This field displays the type of the data item. Each data item is one of nine data types: Byte, Integer, Long, Floating Point, Double-Precision, Complex, Double-Precision Complex, String, or Undefined.

Byte: Unsigned integers from 0 to 255

Integer: Integers from -32768 to +32768

Long: Integers from -231 to 231-1

Floating-Point: Single precision, floating-point with six significant places. Magnitudes range from  10^-38 to 10^38 on machines with IEEE arithmetic or 10^-34 on VAX systems.

Double-precision: Floating point with approximately sixteen decimal digits.

Complex: A real-imaginary pair of floating-point numbers.

Double-precision complex: A real-imaginary pair of double-precision numbers.

String: A sequence of 0 to 32,767 characters.

Undefined

Dimensions

This field displays the number of elements in each dimension of the data item. The field contains one number for a vector and two numbers for an array. For example, the "Dimensions" field contains "60, 60" for a two-dimensional array with 60 elements in one dimension and 60 in the other.

Elements

This field displays the total number of elements in the data item. Basically, the total equals the number of elements in one dimension of the data item multiplied by the number of elements in another dimension. For example, the "Elements" field will contain the number "3600" for a two-dimensional array with 60 elements in one dimension and 60 in the other.

Description

(Optional) This field shows the description you provided when you created the data item.

Update Time

This field displays the date and time of the last modification.

Source

This field displays the source of the data item. This field contains:

•	"command line" if you generated the item from the IDL command line

•	"analysis" if you generated the item from an Analyze dialog

•	"file" if you imported the item

Size

This field displays the number of bytes the data item contains, showing you how much memory the item takes up.

Value

This field displays the value of a scalar. This field cannot be modified .ASSOC File

This field indicates whether or not the data item is an associative file.

Minimum

This represents the minimum value of the data item.

Maximum

This represents the maximum value of the data item.


Saving in the Data Manager Window

Just like a visualization, a data item is just part of the current Insight project. Saving new or modified data really means saving changes to the project. To save changes to the Data Manager window, select "Save Project" from the File Menu of the Visualization window. See "Save Project Menu Option" on page 14.

Hint	As a shortcut you can use the Save button from the Visualization Tool Bar. See "Visualization Tool Bar" on page 34.


Importing and Exporting Data: The Data Manager File Menu

Visualizing Data

Documentation to be completed/added post-Beta

This chapter describes visualization, introduces the Insight Visualization window, menu bar, and tool bar. You will learn how to use the Visualize menu to display data and the View menu to customize how Insight displays those visualizations in the window.


What Is Visualization
What Is Visualization?

The term "visualization" has two basic meanings in Insight:

•	Visualization refers to the general display of data in the Visualization window

•	In addition, any data item displayed (or "visualized") in the Visualization window is called a visualization.

Using the window's Visualize menu options, you can display several types of visualizations: images, line plots, scatter plots, histogram plots, polar plots, contours, and surfaces. See "The Visualize Menu" on page 35.

One or more graphic elements comprise a visualization. An element corresponds to the simplest graphical item displayed.   Elements include axes, grids, and vectors. Visualizations and their elements have properties which determine their appearance. Examples of visualization properties are x and y locations and transparent background. Examples of element properties are line type, line color, and symbol style. You can view and modify properties using the Properties dialog. See "The Properties Dialog" on page 48

You can visualize data in a variety of plot formats, including general x versus y, contour, mesh surface, and perspective plots. Plotting involves one x and one y axis (or radius and Theta for polar plots). You can plot one or more y vectors. The x axes are scaled to fit all the y vectors.

The Visualization Window


The Visualization Window

When you start the Insight application and a new Insight "project" opens, one of the project components, the Visualization window, appears on your screen as a blank viewing area with a tool bar and menu bar.

The Visualization window represents:

•	the primary workspace in which you can visualize data such as line plots, scatter plots, histogram plots, polar plots, contours, images, and surfaces

•	the hub from which you can navigate to:

−	other project components such as the Data Manager window

−	Analyze dialogs which allow you to analyze and generate data


Visualization Tool Bar

The Tool Bar located appears across the top of the Visualization window below the menu bar. When you use the mouse to point to each tool, the name of the tool appears in the lower left-hand corner of the Visualization window. By default, the tool bar automatically appears in the Visualization window when you start Insight. The tool bar features buttons corresponding to various Visualization menu options as well as annotation options. Select a button by clicking it. When a menu option is disabled, the corresponding tool bar button is disabled as well.  For more information about a button, click one of the tool bar options below.

Visualization Menu Bar

The menu bar across the top of the Visualization window groups Insight   operations into six main menus: File, Edit, Visualize, Analyze, View, and Help. When you select a menu option that is followed by an ellipsis (...), Insight opens a dialog or window so you can enter more information or select options before performing an operation. Since this chapter explains how to visualize data, only the Visualize Menu and dialog options.

For help using a specific Visualization window menu, simply click one of the choices below:

Managing Projects: The File Menu

Editing Visualizations: The Edit Menu

The Visualize Menu

The Analyze Menu

The View Menu

Getting Help: The Help Menu


The Visualize Menu

The visualization menu provides options for visualizing data in the Visualization window. Using these options you can visualize line plots, scatter plots, histogram plots, polar plots, contours, images, and surfaces. Each option opens a dialog from which you can select data and specify options. Visualizations are displayed on a right-handed coordinate system. The coordinate system is right-handed so that when looking from a positive axis to the origin, a positive rotation is counter-clockwise. The x axis runs across the display, the y axis is vertical and the positive z axis extends out from the display to the viewer. For example, a 90-degree positive rotation about the z axis transforms the x axis to the y axis. For help using a specific Visualize menu option, you can navigate through this section or jump to a specific topic by selecting from the choices below:

Line Plot Menu Option

Scatter Plot Menu Option

Histogram Plot Menu Option

Polar Plot Menu Option

Contour Menu Option

Image Menu Option

Surface Menu Option


Line Plot
Line Plot Menu Option

Select this option to open a Line Plot dialog from which you can select data and options for drawing a line plot in the Visualization window. A line plot displays the connection of points that comprise a data item.

Using the Line Plot Dialog

Selecting the "Line Plot" option from the Visualize menu opens the Line Plot dialog.

1.	Select one or more data items by selecting the "y axis" box to the left of one or more data items in the data selection list.

Note	Available data includes items you have imported (see "Import File Menu Option" on page 15) or items you have generated using Analyze options (see "The Analyze Menu" on page 62).

If you select only the y axis box for a data item, Insight will label the Visualization's y axis with data coordinates (the dependent data) and label the x axis with the number of elements in the data item. Optional: Additionally select the "x axis" box for any data item in the list. If you select an x and a y, Insight will plot the y (the dependent data) as a function of the x (independent data). The data item for which you have selected the x does not have to have the y selected.

2.	From the "Plot Style" droplist, select a style. Plot Styles determine the "look" of your visualization. For more information on styles, see "Save Style Menu Option" on page 47.

3.	If you want to set up a grid for viewing visualizations, select the desired "Rows By Columns" menu option from the View menu BEFORE you click "OK" in this dialog. "Rows By Columns" options are most useful when you plan to view multiple visualizations simultaneously. The "Rows By Columns" option you select determines how many visualizations you want to view and how they should be displayed. For example, if you plan to view three visualizations simultaneously displayed in one row, select the 1 By 3 (Rows By Columns) option. If you select one of these options after data has been visualized, a grid will appear on top of your current visualization(s).

4.	When you are finished with the dialog, click "OK". The dialog closes and Insight displays the line plot in the Visualization window. To view or modify this line plot, see "Editing Visualizations: The Edit Menu" on page 45 or "Working With Visualization Properties" on page 47.

Zoom In Menu Option

Select this option to magnify your view of the visualization(s) in the window by a factor of 2. Select this option until you reach the desired magnification. Each time you select this option, Insight magnifies the view of the visualization by a factor of 2. When you zoom in, you are not simply enlarging pixels but performing a smooth interpolation; therefore, each zoom may take a few seconds. The maximum magnification is 1280 x 1024 pixels.


Zoom Out Menu Option

Select this option to reduce the view of the visualization(s) in the window by a factor of 1/2. Select this option until you reach the desired reduction. Each time you select this option, Insight reduces the view of the visualization by 1/2. There is no maximum reduction.

Remember that when you use zoom options, you are not actually changing the size of the visualization - only your view of the visualization.

Selecting and Using Visualizations

More TBA post-Beta documentation


Editing Visualizations: The Edit Menu

The Edit menu provides options for changing the appearance of visualizations. Using these options, you can define colors, modify properties of visualizations, view styles, save styles, and undo/redo.


Undo Menu Option

Select this option to reverse the previous action. Insight alerts you before executing a command you cannot undo. You have the option to undo an action until your next mouse click.


Redo Menu Option

Select this option to reverse the previous action. This option is used usually after the Undo option has been selected.


Delete Menu Option

Select this option to remove a selected item (visualization or element) without storing it in memory.   Until your next mouse click, you can select the Undo option to reverse this action.


Duplicate Menu Option

Select this option to duplicate a selected item (visualization, element, or data item).


Visualization Manager Menu Option

Select this option to open a Visualization Manager dialog which allows you to delete or edit elements or entire visualizations.

Using the Visualization Manager Dialog

1.	The "Graphics" list on the left-hand side of the dialog displays the name of each visualization in the window followed by the names of all its elements. If you highlight a name in the list, Insight automatically selects that item in the Visualization window. Click the name of the element or visualization you'd like to delete or edit.

2.	Select the desired button: "Delete" or "Edit."

•	To delete the item, click "Delete." Insight deletes the item from the Visualization window. (Before your next action, you can select the "Undo" option from the Edit menu to reverse the delete.)

•	To edit the properties of the selected item, click "Edit." A dialog opens displaying properties for the selected item. Edit Properties as desired. For more information on modifying Properties see "The Properties Dialog" on page 48

You may leave the Visualization Manager dialog open during your session. A new Visualization Manager dialog opens each time you select the "Visualization Manager" option from the Edit menu. Click "Close" to close the dialog.


Insert Graphic Menu Option

Select this option to open an Insert Graphic dialog which allows you to select one or more data items to insert into a visualization. Before selecting this option you must first select a visualization or one of its elements in the Visualization window into which you'd like to insert a new visualization.

Using the Insert Graphic dialog

1.	Select a data item by selecting the "y axis" box to its left.

2.	Optional: Select the "Adjust Range" option if you want the axes to adjust to the range of all existing plot lines in the Visualization window as well as to the plot lines you are inserting. If you don't select this option, the plot lines are clipped to the range of the existing plot lines in the window.

3.	When you are finished, click "OK". The dialog closes and the graphic element is inserted into the selected visualization.


Apply Style Menu Option

Select this option to view of submenu of Styles.

More TBA post-Beta documentation


Save Style Menu Option

Select this option to open the Save Graph Style dialog which allows you to save the properties of a selected visualization as a style. To save the new style to a name other than the default name listed in the "Name" text field, click in the text field and edit. (You also can double-click in the text field to highlight all of the existing text and enter a new name.) The style is saved to a list which can be accessed by selecting the "Apply Style" option from the Edit menu.


Properties Menu Option

Select the this option to open a Properties dialog which allows you to inspect and modify the unique properties of a selected visualization or element. The Properties menu option contains the name of the selected item. For example, if you have selected an entire line plot visualization in the window, the menu option will read "<Line Plot Graph Visualization> Properties." If you have selected just the line in the window, the menu option will read "<Data Plot Line Visualization> Properties." See Working With Visualization Properties.

Note	You also can open a Properties dialog by double-clicking the visualization or element. For a visualization, double-click within the visualization's bounding area. A bounding box will appear indicating that the visualization has been selected. To open a Properties dialog for an element, simply double-click on that element.


Working With Visualization Properties

Properties are characteristics of a visualization that determine how it looks. Select the "Properties" option from the Edit menu to open a Properties dialog which allows you to inspect and modify the unique properties of a visualization or element selected in the Visualization window. This section describes the dialog controls that represent those properties.

Note	You also can open a Properties dialog by double-clicking the visualization or element. For a visualization, double-click within the visualization's bounding area. Highlighting will appear indicating that the visualization has been selected. To open a Properties dialog for an element, simply double-click on that element.


The Properties Dialog

The Properties dialog provides controls you can use to modify properties of selected elements or visualizations. The controls displayed depend on the visualization or element selected. This section groups dialog controls into visualization types:

Dialog controls for general properties of a visualization appear when you open the Properties dialog with the entire visualization selected. These properties are associated with all visualizations. You can view and change properties such as name, location in the window, and background transparency. See "Dialog for General Visualization Properties" on page 48.

Dialog controls for Line Plot properties appear when you open the Properties dialog with a line plot selected. See "Properties Dialog for Line Plots" on page 50.

Analyzing Data

Documentation to be completed/added post-Beta

This chapter introduces data analysis with Insight and tells you how to use Analyze menu options to correlate data, fit curves, process images, and smooth data.

What is Data Analysis in Insight?

Insight has incorporated IDL analysis capabilities into the Analyze menu and dialog selections. As you work on technical problem solving, you can use Analyze menu options to manipulate and analyze existing data and generate new data. Most of the time, you need only select the desired menu and dialog options. Insight performs the coding "underneath" to perform analyses and generate new data based on your dialog selections.

Note	To view a newly-created data item and its attributes, simply open the Data Manager window. To open the Data Manager window, see "Data Manager Menu Option" on page 15. To find out more about this window, see "Working With Data" on page 21.

Using Analyze menu options, you can open dialogs which allow you to correlate, smooth, and fit curves to data; and process images. Insight performs analysis operations by selecting the desired Analyze menu option. A dialog opens which allows you to:

•	select existing data items, algorithms, and other information with which you'd like to work

•	choose how you'd like to view analysis results

•	apply computational operations to numeric data types

Viewing Analysis Results

You can view analysis results in several ways. You may choose to:

•	automatically visualize the data in the Visualization window. (As specified in this chapter, some data cannot be visualized.)

•	automatically view a "Summary" dialog which displays the data result immediately after Insight has completed your analysis operation. (As specified in this chapter, some types of analysis operations do not have Summary dialogs.)

•	select the "Data Manager" option from the File menu in the Visualization window. The Data Manager window lists all data items which have been generated in Analyze dialogs and stored in Insight's data area.

Note	Clicking "OK" generates new data while clicking "Apply" does not. See "The Insight Interface: Standard Insight Dialog Buttons" on page 7.

Using the Visualization Window as an Analysis Tool

You can use the Visualization window as an Analysis tool in several ways:

•	First select a visualization already displayed in the Visualization window. Then select an Analyze menu option to open a dialog. In the dialog's "Dependent" text field, Insight automatically displays the name of the selected visualization.

•	By selecting an Analyze menu option first, you can open a dialog and then select a data item on which to perform an analysis. You can visualize the new data in the Visualization window. Insight gives you options for either clearing the Visualization window and displaying your new visualization or inserting a new visualization into an existing one. (As specified in this chapter, some data types cannot be visualized or inserted.)

The Analyze Menu

Chapter TBD Using IDL (Correlation Analysis)


The Analyze Menu

The Analyze menu provides options for performing data analysis and generating data. Using these options, you can correlate data, fit curves, process images, and smooth data. You also can generate new data items, new visualizations, and/or analysis summaries.

Correlate Menu Option

Select this option to open a dialog which allows you to correlate data. The dialog options displayed depend on the algorithm selected. When you select an algorithm from the dialog's Algorithm droplist, the unique options associated with that algorithm appear.

What is Correlation?

Correlation involves quantifying the "likeness" or "degree to fit" of one or more sample populations to an ideal linear model or to other sample populations. The measure of likeness may be based upon the actual data values or upon their magnitude-based ranks. Based on criteria you specify in the Correlate dialog, Insight automatically computes the correlation and opens a window showing the correlation value. For example, an output value of 1 indicates a perfect positive linear correlation; an output value of -1 indicates a perfect negative linear correlation; an output value of -0.98 indicates a high negative linear correlation; and an output value close to zero indicates a poor linear correlation.

The Correlate Dialog

When you select the "Correlate" option from the Analyze menu, a dialog opens which allows you to select algorithms, specify data, and generate new data items. This chapter describes the unique Correlate dialog options for each algorithm.

About the Algorithms

The Correlate dialog contains an Algorithm droplist from which you may select an algorithm for your output data.   Each algorithm has its own unique dialog options. Insight provides three types of algorithms: Correlation, Covariance, and Correlogram.

Correlation algorithms:

•	output data using these algorithms cannot be visualized

•	Summary dialogs can be viewed

•	Algorithms include: Auto Correlation, Cross Correlation, Kendall Correlation, Linear Correlation, Linear Correlation Matrix, Multiple Correlation, Partial Correlation, and Spearman Correlation

Covariance algorithms:

•	Output data using these algorithms cannot be visualized.

•	Summary dialogs can be viewed.

•	Algorithms include: Auto Covariance, Cross Covariance, Linear Covariance, and Linear Covariance Matrix.

Correlogram algorithms:

•	Output data using these algorithms can be visualized.

•	Summary dialogs cannot be viewed.

•	Algorithms include: Auto Correlogram and Cross Correlogram

For help using a specific dialog, you can navigate through this section or jump to a specific topic by selecting from the choices below:

Dialog For Auto Correlation
Using the Correlate Dialog for Auto Correlation

Algorithm Droplist

From the Algorithm droplist, select Auto Correlation. This Correlation cannot be visualized; however, a Summary dialog is available.

Independent Text Field

In the "Independent" text field, enter a data item or click "Browse" to open a Browser of data items from which to choose. If you have selected a data in the Visualization window, the name of this data item automatically appears in this text field.

Independent Browse Button and Data Browser Dialog

Click "Browse" to open a Data Browser which contains a scrolling list of data items. Select one item and click "OK."   The dialog closes and the name of the selected data item appears in the text field to the left of the "Browse" button.

Note	You will notice that the Browser lists two- and three-dimensional options when choices must be one-dimensional. Insight views two and three-dimensional data items as sets of one-dimensional vectors. If you select a two or three-dimensional data item, Insight uses the one-dimensional vectors in the analysis.

Lag Text Field

In the "Lag" text field, enter the offset as a floating point value. Lag represents a time difference between elements in a dataset and indicates how far to look behind or ahead in time. With lag, x becomes a temporal variable. For example, a lag of 1 could specify the temporal distance between indexed elements 1 and 2; a lag of 2 then could specify the temporal distance between indexed elements 1 and 3.

Summary On/Off Box

Selecting this option opens a Summary dialog which displays output information immediately after Insight has completed your analysis operation.

If you have performed the analysis by clicking "Apply" in the Analyze dialog, clicking the Summary dialog's "OK" button will close the Summary dialog. The Analyze dialog will remain open.

If you have performed the analysis by clicking "OK" in the Analyze dialog, clicking the Summary dialog's "OK" button will close the Summary dialog and the Analyze dialog.

More Button

Click this button to view additional options for performing the analysis.

Less Button

Click this button to close the extended dialog that displays additional options for performing the analysis. The dialog displaying the basic dialog options remains open.

Outputs Text Field

(This option appears when you select the dialog's More button.) To save the new data generated by this analysis to a name other than the default name listed in the text field, click in the text field and edit. (You also can double-click in the text field to highlight all of the existing text and enter a new name.)

Outputs Browse button

(This option appears when you select the dialog's More button.) Select this button to open a data browser which contains a scrolling list of data items. Select one item and click "OK."   The dialog closes and the name of the selected data item appears in the "Outputs" text field.

To Perform the Analysis

After you have finished selecting options in the Analyze dialog, you can perform the operation in either of two ways:

1.	Click "Apply" to perform the operation as a trial, without generating a new data item.

This option is helpful when you want to "try out" various options  before generating a data item to be stored and listed in the Data Manager window.   A Summary dialog, if requested, displays the result. Clicking the Summary dialog's "OK" button closes the Summary dialog.   However, the Analyze dialog remains open so you can modify your criteria and use the Apply option as many times as you wish. When you're ready to generate a new data item, click "OK."

2.	Click "OK" to generate and store a new data item.

A Summary dialog, if requested, displays the result. Clicking the Summary dialog's "OK" button closes the Summary dialog and Analyze dialog.   To view the data item's name and attributes, open the Data Manager window.

Note	Multiple data items cannot be generated during a single dialog session. A single dialog session is the time period between opening and closing a dialog. After clicking "OK" you can perform another Analysis (and generate another data item if desired) by selecting an Analyze menu option to open or reopen a dialog.

Where is Data Stored?

Once the analysis operation has been completed and permanently applied by clicking "OK" Insight creates a new data item representing the output of the analysis and lists it in the Data Manager window. To view and modify the data item's attributes, see "The Data Manager Window Menu Bar" on page 22.

Fit Curve Menu Option

Select this option to open a dialog which allows you to fit a curve to data. The dialog options displayed depend on the model selected. When you select a model from the dialog's "Model" droplist, the unique options associated with that model appear.

What is Curve Fitting?

With Curve Fitting, you can find an analytic representation (or Model) which represents data more compactly. Basically, this involves fitting your data and a specific type of curve to each other. Typically, your data is already plotted in the Visualization window or you understand how a plot of the selected data appears. Using Insight's Fit Curve dialog, you can scroll through a list of models to find the best representation of your data. As you select each model name, its graph and associated mathematical formula is displayed on the right-hand side of the dialog.

After specifying all dialog information, you may visualize the curve fitting in the Visualization window and view results in a Summary dialog.


The Fit Curve Dialog

When you select the "Fit Curve" option from the Analyze menu, a dialog opens which allows you to select models, specify data, and generate new data items. This chapter describes the unique Fit Curve dialog options for each model.

About the Models

The Fit Curve dialog contains a "Model" droplist from which you may select a model curve. The selected model's name, formula, and example is displayed on the right side of the dialog. You will fit the selected curve to your data (and/or the data to the curve.) Each model has its own unique dialog options that allow you to specify additional criteria for fitting the curve.

To Perform the Analysis

After you have finished selecting options in the Analyze dialog, you can perform the operation in either of two ways:

1.	Click "Apply" to perform the operation as a trial, without generating a new data item.

This option is helpful when you want to "try out" various options or visualize the data before generating a data item to be stored and listed in the Data Manager window.   A Summary dialog, if requested, displays the result. Clicking the Summary dialog's "OK" button closes the Summary dialog.   However, the Analyze dialog remains open so you can modify your criteria and use the Apply option as many times as you wish. When you're ready to generate a new data item, click "OK."

2.	Click "OK" to generate and store a new data item.

A Summary dialog, if requested, displays the result. Clicking the Summary dialog's "OK" button closes the Summary dialog and Analyze dialog.   To view the data item's name and attributes, open the Data Manager window.

Note	Multiple data items cannot be generated during a single dialog session. A single dialog session is the time period between opening and closing a dialog. After clicking "OK" you can perform another Analysis (and generate another data item if desired) by selecting an Analyze menu option to open or reopen a dialog.

To Perform the Analysis

After you have finished selecting options in the Analyze dialog, you can perform the operation in either of two ways:

1.	Click "Apply" to perform the operation as a trial, without generating a new data item.

This option is helpful when you want to "try out" various options or visualize the data before generating a data item to be stored and listed in the Data Manager window.   A Summary dialog, if requested, displays the result. Clicking the Summary dialog's "OK" button closes the Summary dialog.   However, the Analyze dialog remains open so you can modify your criteria and use the Apply option as many times as you wish. When you're ready to generate a new data item, click "OK."

2.	Click "OK" to generate and store a new data item.

A Summary dialog, if requested, displays the result. Clicking the Summary dialog's "OK" button closes the Summary dialog and Analyze dialog.   To view the data item's name and attributes, open the Data Manager window.

Note	Multiple data items cannot be generated during a single dialog session. A single dialog session is the time period between opening and closing a dialog. After clicking "OK" you can perform another Analysis (and generate another data item if desired) by selecting an Analyze menu option to open or reopen a dialog.

Process Image Menu Option

Select this option to open a dialog which allows you to process images. The dialog options displayed depend on the algorithm selected. When you select an algorithm from the dialog's Algorithm droplist, the unique options associated with that algorithm appear.

What is Image Processing?

Image processing uses various methods to filter and transform image data. An image consists of a two-dimensional array of pixels. The value of each pixel represents the intensity and/or color of that position in the scene. Images of this form are known as sampled or raster images because they consist of a discrete grid of samples. Such images come from many sources and are a common form of representing scientific and medical data.   Images often are stored as arrays of bytes and easily can be represented as two-dimensional arrays.

Insight Tutorials

Documentation to be completed/added post-Beta

This chapter teaches you how to perform common Insight operations, providing examples demonstrating broad categories. You'll learn how to access and condition data, visualize data and modify properties, and perform several types of data analysis.

Before you read through these tutorials, you should review the descriptions of how to Visualize Data (Chapter 5), edit Visualizations (Chapter 6), Analyze Data (Chapter 7), and work with data in the Data Manager Window (Chapter 4). You should also have a good idea of how to work with the interface features (Chapter 2). These sections describe Insight's dialog options and provide hyperlinks to additional documentation (such as descriptions of IDL routines and pictures of examples and dialogs).


Working With Data in the Data Window Tutorial
Working With Data in the Data Manager Window Tutorials

post-Beta documentation


Accessing Data Tutorial

Using Insight you can access Insight data files (already in the Data area) in one of two ways:

1.	Working in the Visualize window and using its menu and dialog options

When you select the Visualize or Analyze menu options, dialogs open that provide browsers for you to select data items to visualize or analyze.

2.	Working in the Data Manager Window and using its menu and dialog options

When you select the "Data Manager" option from the File Menu in the Visualization window, the Data Manager Window opens. Using this window's menu options, you can directly work with data, view each data item and its properties, and organize your view of the data listings.

Note	Remember that you can open both windows and work with them simultaneously. For example, suppose you have a data item visualized in the visualization window. You can open the Data Manager Window, modify the properties of that data item, and re-visualize. The second visualization will reflect your modifications to the data.

Insight API
Insight's API

Documentation for all sections in this chapter to be completed/added post-Beta

This chapter describes the Insight routines you can use to invoke and interact with Insight from the IDL command line or from within a PlugIn. You should have a working knowledge of IDL to use these routines.

Insight API routines documented in this chapter are Insight, InsPut, InsGet, and InsVis. A description of each routine follows its name. Beneath the general descriptions are sections that specify the routine's calling sequence, its arguments, and its keywords. All keywords are optional unless specified as required.

See Also:

"Extending Insight" on page 191.

Chapter TBD Using IDL ((TBA)

IDL Reference Guide (TBA)


Insight Routine

Use the INSIGHT routine to start Insight from the IDL command line. Optionally, you can use this routine to pass data from IDL into Insight upon startup.

Calling Sequence

Insight, [Var1, ..., Varn]

Arguments

Var1 ... Varn

Individual IDL variables to be imported into Insight.

Caution	1. Associated variables (created with the IDL ASSOC function) are not allowed.

2. Structure variables must contain only data (no pointers, object references, or substructures).

Keywords

IMPORT_FILE (Input)

Set this keyword equal to a string containing the name of a data file to import into the project. Default: If this keyword is not specified, Insight will not import a data file.

Note	When Insight starts, a Select Data To Import dialog opens which allows you to select data to import.See "Using The Select Data To Import Dialog" on page 12.

LANGUAGE_FILE (Input)

PLUGINS_DIR (Input)

Set this keyword equal to a string containing the name of the directory where PlugIn files reside. Default: Insight uses the PlugIns directory specified by the user in Insight's Preferences dialog. See Preferences: "Using the Preferences Dialog To Specify the PlugIns Directory" on page 17.

PREFERENCE_FILE (Input)

Set this keyword equal to a string containing the name of the location of the user preference file. If set, this keyword overrides the system default preferences. Default: Insight uses the default Preferences file, if one exists.

PROJECT_FILE (Input)

Set this keyword equal to a string containing the filename of the project. Default: If this keyword is not specified, a new project opens.

Note	When Insight starts, a Getting Started With Insight dialog opens which allows you to select an existing project or open a new project. See "Using The Getting Started With Insight Dialog" on page 11.


InsPut Routine
InsPut

Use the InsPut procedure to put user data into Insight from the IDL command line or from within a PlugIn (File or Analysis).

Calling Sequence

Insput, [Var1, ..., Varn]

Arguments

Var1 ... Varn

Individual IDL variables containing the names of the data items to be imported into Insight. Default: If no arguments are passed in, a Choose Insight Data dialog opens which allows you to select data items from a browser.

Caution	1. Associated variables (created with the IDL ASSOC function) are not allowed.

2. Structure variables must contain only data (no pointers, object references, or substructures).

Note	You can change the title of this dialog. See "TITLE (Input)" on page 187.

Keywords

Extending Insight

Documentation for all sections in this chapter to be completed/added post-Beta

This chapter describes how you can add functionality to Insight by creating PlugIns. Detailed knowledge of Insight's underlying code architecture is not required to build a PlugIn; however, PlugIn authors must:

•	have a working knowledge of IDL, and

•	follow the Insight PlugIn development guidelines described in this chapter.

Insight PlugIn routines use wrapper routines which are described in Chapter 9 Insight API.

About Insight PlugIns

A PlugIn is a routine written in the IDL language. PlugIns must follow Insight's PlugIn conventions as described in this chapter. PlugIns must follow Insight's PlugIn conventions as described in this chapter. The three types of Insight PlugIns are:

•	File (See "File PlugIns" on page 193)

•	Conditioning (See "Conditioning PlugIns" on page 194)

•	Analysis (See "Analysis PlugIns" on page 195)

Installing PlugIns

Documentation to be added post-Beta

Installing a PlugIn into Insight requires little more than putting the code file in a directory and telling Insight where to search. The steps are simple:

1.	Select the "Preferences" option from the File Menu in the Visualization window. The Preferences dialog opens.

2.	Select the "PlugIns Customization" option from the "Category" droplist to specify the file where PlugIns will be placed. The PlugIns Customization dialog options appear.

Select the directory in which PlugIns reside in one of the following ways:

•	Enter a path in the "PlugIns Directory" text field, and click "OK." The dialog closes.

•	Click "Browse" to open a browser. Select a directory and click "OK." The browser closes. Click "OK" to close the Preferences dialog.

The next time you start the application, Insight will search for valid PlugIn files in the directory specified.

See Also:

Preferences Menu Option

As long as you continue to place new PlugIn files in that same directory or folder, Insight automatically loads them the next time you start the application.

Note	 If you place a new PlugIn file in the designated directory or folder during an Insight session, it will not be loaded into Insight until you restart. However, during a session you can modify and compile an existing PlugIn file and use its new functionality without restarting Insight. Just make sure you don't modify the PlugIn's registration routine; for example, the callback names must remain the same.

Removing PlugIns

To remove a PlugIn from Insight, simply remove it from the PlugIns directory. The next time you start Insight, the PlugIn will not be available.


Guidelines for Writing PlugIns
Insight Guidelines for Writing PlugIns

Documentation to be added post-Beta

Detailed knowledge of Insight's underlying code architecture is not required to build a PlugIn to Insight. However, you must follow specific development guidelines for each type of PlugIn: File, Conditioning, and Analysis. Guidelines and examples for each type are described in this section.

Conditioning PlugIns

Conditioning PlugIns perform mathematical operations on Insight data items selected in the Data Manager window. For example, you can write a PlugIn that rotates a selected data item by 90 degrees. Insight includes these PlugIns as menu options listed in the Condition menu. (Another Example TBA).

Conditioning PlugIns require the following routines:

1.	Event Handling Routine(s)

2.	Main Function Callback

3.	Registration Function
