It sounds like what you are asking for is a reversed colormap, and all the standard colormaps included with mpl have reversed forms. The pylab interface does not provide functions for the reversed forms, but it does allow one to specify any of the reversed forms. To use a reversed gray colormap, for example, one might do something like this: import matplotlib.pyplot as plt import numpy as np img = plt.imshow(np.random.rand(10, 12)) img.set_cmap(plt.cm.gray_r) plt.colorbar() plt.show() Eric ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
