Hi, I once was indicated a way to extract colors from exsiting colormaps: I just answered a question on Stackoverflow and maybe you can have a look.
all code in pylab mode a = np.arange(100).reshape(10,10) #here is the image with white and black end imshow(a,cmap=mat.cm.binary) colorbar() #we extract only the 0.2-->0.7 part of original colormap and make a new one #so that the white and black end are removed rgba_array = mat.cm.binary(np.linspace(0,1,num=10,endpoint=True)) extract_rgba_array_255 = rgba_array[2:8,0:3] imshow(a,cmap=mat.colors.ListedColormap(extract_rgba_array_255)) colorbar() cheers, Chao -- View this message in context: http://matplotlib.1069221.n5.nabble.com/colormap-shift-tp39660p39707.html Sent from the matplotlib - users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Everyone hates slow websites.
