YAXISCOLOR

Syntax: | `SET YAXISCOLOR n SET YAXISCOLOR colorname GET YAXISCOLOR { n }`
Default: | `YAXISCOLOR =` black

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

`YAXISCOLOR` controls the color of the y-axis. The parameter `c` can be a numeric scalar or one of the fixed color names.

For example:

`SET YAXISCOLOR 2` uses the colormap index 2
`SET YAXISCOLOR RED` uses the fixed color name "RED"
