Reverse colormap in matplotlib
I would like to know how to simply reverse the color order of a given colormap in order to use it with plot_surface.
Solution 1:
The standard colormaps also all have reversed versions. They have the same names with _r tacked on to the end. (Documentation here.)
Solution 2:
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')
