Hi, I am using matplotlib for all my figure needs in academic papers, but I would like to convert some of my figures (generally exported ni eps and pdf) in black and white. I tried using colormaps, but when using several axes, I can't convert them all in one shot. Is there any way to say (in say savefig) to use a given colormap (gray levels in my case) for the whole figure ? Or is colormap not the way to go ? thanks, David
