I'm guessing it wouldn't be too uncommon for a user to want to have two images on the screen with different colormaps. For example: subplot(2,1,1); image; colormap(gray(64)); subplot(2,1,2); image; colormap(ocean(64)); This requires the latest CVS version of gnuplot as there was just an upgrade to allow multiple colormaps in X11. Most other file-based terminals should work. There may be some GUI-based terminals that don't yet work. If so, let me know.Is there a sensible fallback for older versions of gnuplot? What happens with the attached patch when used with both 4.0 and 4.2?
For older versions the colormap of both images (in this example) will be the most recently set, i.e., similar to current behavior as though colormap is associated with the figure, not the axes. So, there really isn't any code necessary to fall back to current behavior in the case of 4.0 and 4.2. Dan
