-----------------------------<  About  PLOT  >--------------------------------

PLOT is used to plot the data interactively.  This interface is brought up when
the button 'PLOT' is clicked at the MAIN interface.  The names of the selected 
CDF files and key parameters are displayed for each panel.  If a selected file 
contains more than one-day worth of data, the day of year boundaries are also 
displayed.  Since the data is plotted in a 24-hour time frame, to specify the 
date is needed in this case.  The default value is the first day of the year 
contained in that file.  The majority of CDF files in ISTP contains only 
one-day worth of data.  The only exception so far is the CDF files from IMP-8. 


Option: " SELECT Day of Year(for multi-day file only) "
------
 
This option is used to specify the desired 'day of the year' and 'year' for the
data to be plotted.
    
         FORMAT: 'day of year': 1-365(366)
                 'year'       : 'YYYY'
         
         For example: Day 24 of 1994 
                 

Option: " GO! "
------ 

This option is used to load and plot the data.


Option: " Cancel " 
------

This option is used to cancel the selections and exit from this interface.


Option: " Help " 
------

This option is used to display the help information.


To Use:  

       Step 1:  ( Omit this step if no multi-day CDF file is selected.)

            Highlight the dialog boxes of the day and year selections and then 
            type in the desired values.
        
       Step 2:  Click 'Go!' to plot the data or 'Cancel' to cancel the action.
