DESCRIPTION

This command controls color attributes for those devices which can display a large number of colors. The data color is the color that is used when plotting the data files. The data color may be automatically incremented from a color list after each data file is plotted. The skeleton color is the color used to plot and label the axes, titles, grids, and frame ids. The backgound color is the color of an empty frame, before any lines or text are plotted.

Most of the time you will select the name of a standard color, such as red or blue. This will be the color, independent of the selected graphics device. At times, however, you may want to choose a non-standard color, such as aquamarine. This can be done by "downloading" a color table to the graphics device. This color table associates a specific hue, saturation, and lightness with a specific integer number. You can then select aquamarine for a particular part of the plot by setting that attribute to the correct number from the color table. This may sound like a lot of work, but if aquamarine is your favorite color, it may be worth it.

If you are plotting several data files on the same plot, you may want each to be in a different color. This is done using the INCREMENT option. When this option is on, the data color is incremented from a list of colors each time a data file is plotted. The order of colors in the standard or default color list is given below:

RED, GREEN, BLUE, YELLOW, CYAN, MAGENTA, BLACK

You may change the order or content of this color list using the LIST option. This is useful if you are doing a series of overlay plots (see PLOT2) and want the same colors used in the same order on each plot.

EXAMPLES

To select an incrementing data color starting with red:

SAC> COLOR RED INCREMENT

To select red data colors on a white backgound with a blue skeleton:

SAC> COLOR RED BACKGROUND WHITE SKELETON BLUE

To set up an incrementing data color list of red, white, and blue with an aquamarine (!!!) background:

SAC> COLOR RED INCREMENT BACKGROUND 47 LIST RED WHITE BLUE

The above example assumes that aquamarine is color 47 in the color table for the selected graphics device. Background color is currently being ignored.
