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 `i`th 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"
