Hi,
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 ?
Xavier
