Surfaces, Images, Plots, Accumulated plots

All displays may be edited, in order to change/customize their appearence (colors, fonts, etc..). This is possible when cliking on the graphical objects (figures, axes, images, surfaces, plots, legends, text...)
Also, when selecting a curve, the mouse position is indicated below the graph.
You may resize the whole Display Panel, but this is rather slow and its probably better not to have too big displays.

These options are to be used when calling the "display" command:

    display, Data=<data set>, Name_Data="<Data set Name>", [Options]
with:

Options=</log,/scatter,/histogram,/polar>
        </add,/overlay,/catenate,/unactivate,/exact,/no,/delete>
        <IX=[expr], IY=[expr], Name_IX="...", Name_IY="..."
         Comment="...", Auto_Load="...">
   sets some display options to use.
   options that affect Data
      IX=[expr] sets the expression/variable to use as X axis values (for 1D/2D data sets)
      IY=[expr] sets the expression/variable to use as Y axis values (for 2D maps)
      Name_IX="..." sets the name of X axis (when IX is given)
      Name_IY="..." sets the name of Y axis (when IY is given)
      Name_Data="..." sets the name of the Data set (default is the Variable name)
      Auto_Load="..." sets the expression to be evaluated before each update
      Comment="..." sets a comment to appear on plot
   options that affect the way data is stored. Default is to replace data.
      /add: to add (sum-up) new data with the existing one
      /overlay: to display new data set on the same axis system
      /catenate: to append new data with previous one
      /unactivate: do not update/display data
      /delete: delete data set/display
      /no: remove the other options from data/plot options list
   options that affect the way the display appears
      /scatter: only plots symbols (default is line and symbols)
      /histogram: plots data as an histogram (steps)
      /polar: plots data in polar coordinates, when IX is given
      /detached: when a new plot will be created, it will appear as a separate window
      /exact: the [XYZ] axis will be tight around data

You may not modify these options from Display itself, but from the clients (for instance Light). Some of the settings may be changed from the property windows poping-up when cliking on the graphical objects (figures, axes, images, surfaces, plots, legends, text...)

Display may export displays and plots in different formats.

Image: Creates an image file of the selected display/data as BMP, GIF, JPEG, PICT, PNG, TIF and SUN.
PostScript: Either sends the display/data for printing or into a PS file as EPS (recommended) or HPGL.
Text: The selected display/data set is stored in text form into a file. This file may be read for data analysis.

This option will automatically update all data sets/displays (with Frequency specified in Preferences) for non overlayed Displays (having only one data set).

This option will automatically save all data sets as text files (with each display is updated)
