Does anyone know how to get the PLOTS routine to use a given color? Specifically, when
the device is in xor drawing mode?
Here's what I'm doing :
0) Defining and loading (via TVLCT) my red, green, blue values.
1) Creating a draw widget and using PLOT and OPLOT to plot my data (in various colors).
This widget has a button attached to it that toggles linking/unlinking the symbols drawn by
OPLOT.
2) When the link/unlink message is received, the device (X Windows display) is set to xor mode
(of course first saving the current graphics function), and then PLOTS is called to draw
lines from point to point (not all the points are to be connected). Here is where I have
problems getting PLOTS to use the color I want. I've tried to find a pattern to its
behavior, but to no avail.
Any help would be greatly appreciated.
