Your first method is not working on my box (no change) but the second one is just fine :) However, it is not as intuitive as other matplotlib ways of doing things. Is there a simple way to modify the colorbar code to get something like colorbar(fontsize=20) work ? Or maybe as a method like that : cb=colorbar() cb.set_fontsize(20) Any comments ?
