Reverse colormap in matplotlib

Question

I would like to know how to simply reverse the color order of a given colormap in order to use it with plot_surface.

Answer 1

The solution is pretty straightforward. Suppose you want to use the "autumn" colormap scheme. The standard version:

cmap = matplotlib.cm.autumn

To reverse the colormap color spectrum, use get_cmap() function and append '_r' to the colormap title like this:

cmap_reversed = matplotlib.cm.get_cmap('autumn_r')
