Your message came more than a month ago, but it looks like no one answered, so here is an answer: with ipython -pylab: imshow(2*rand(10,10) - 1, vmin=-1, vmax=1) cbar = colorbar(ticks=[-1,0,1]) cbar.ax.set_yticklabels(['unstable', 'neutral', 'stable']) draw() - 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
[Matplotlib-users] colorbar tick labeling
I was wondering if it is possible to change the colorbar tick labeling in matplotlib from numeric to text. Essentially, I want the colorbar to be a qualitative indicator; in the jet scheme, I'd like blue to be labeled as 'unstable', green as 'neutral', and red as 'stable'. I can change it so I just show the underlying values - colorbar(ticks = (-1, 0, 1)), but I cannot change the the tick labels to text. Is there any way to accomplish this? Thanks in advance for any help. - 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
