Hi Eric, Thanks much - I'll try that.

Thanks agan. > Karl, It sounds like you need to specify the norm=colors.NoNorm() argument. http://matplotlib.sourceforge.net/api/colors_api.html?highlight=nonorm#matplotlib.colors.NoNorm Then if your data are integers (typed as integers, not just taking integer values), they will be interpreted as indices into the color table. You will probably also want to generate that table yourself and specify it via the cmap=my_cmap kwarg. If you have only a few values, then you may want to generate it as a colors.ListedColormap: http://matplotlib.sourceforge.net/api/colors_api.html?highlight=listedcolormap#matplotlib.colors.ListedColormap http://matplotlib.sourceforge.net/examples/api/colorbar_only.html?highlight=listedcolormap It looks like we don't have any good examples sitting around showing the use of NoNorm; but try it anyway.
