Re: [Matplotlib-users] colorbar() fix limit on Heat map
Jeff, That worked perfectly ! Thank you. One more question... how would I change the colour scheme of the colorbar()?

If you are using contourf, just specify the contour levels to span the range 0-1 (i.e. clevs=linspace(-1,1,15)). -Jeff -- Jeffrey S.

[Matplotlib-users] colorbar() fix limit on Heat map
Hi All, You may remember from my previous post I was having problems plotting a heatmap, however Pete came through for me and made it work. Anyway, I have almost finished what I want to do. The only issue is fixing the colorbar() range limit. Sometimes the my values are 0.01 to 0.2 for example, and other times there 0.01 to 0.99. So what happens it the colorbar() automagically adjusts the gradient according to my values, however I do not want it to do that, I want the graph to be consistantly 0 - 1 (blue - red). I have tried things like colorbar(0,1), however no luck. If you could let me know how to fix the range, I would be very grateful.
