Don't worry, I'm usually worse myself. And his answer did help me. I actually googled the same query, but I skipped over the first two matches after reading the title since I thought they'd just lead me to examples/pylab_examples/show_colormaps.html (which I already found and deemed to be not helpful). > Nick, this is a pretty good example: > > http://matplotlib.sourceforge.net/examples/api/colorbar_only.html If I understand correctly, this explains how to create a discrete colormap, which isn't quite what I want. But with the two links I can figure it out the rest, thanks to both of you!
