PLOTSYMBOLCOLOR

Syntax: SET PLOTSYMBOLCOLOR n
SET PLOTSYMBOLCOLOR colorname
GET PLOTSYMBOLCOLOR { n }
Default: PLOTSYMBOLCOLOR = black

Note: The GET PLOTSYMBOLCOLOR command always returns the color index, and not the color name, even if PLOTSYMBOLCOLOR was set with a color name.

PLOTSYMBOLCOLOR controls the color of the plotting symbols drawn when the GRAPH command is entered. The parameter n can be either a fixed color name, a numeric scalar, or a numeric vector. If n is a fixed color name or a numeric scalar, every symbol will have the same color.

A positive numeric value represents the index of the color in the currently loaded colormap.

A negative number represents the index of the fixed color.

A string value should be one of the fixed color names.

If n is a numeric vector, the ith symbol's color will be n[i], where n[i] > 0 represents the index of the color in the currently loaded colormap, while n[i] < 0 represents the index of the fixed color. In the vector case, the length of n must be the same as the length of the data vectors being plotted.

For example:

SET PLOTSYMBOLCOLOR 2 uses the colormap index 2
SET PLOTSYMBOLCOLOR -2 uses the fixed color index 2
SET PLOTSYMBOLCOLOR RED uses the fixed color name "RED"
