Hello, I am having trouble figuring out how to create a color scale that will be consistent across multiple contour plots. What I would like is to plot a series of contour or image plots for different subsets of a data set but make sure that the color key stays fixed so that the plots are easily comparable. That is I need a map from the range of values of the entire data set to the color scale and keep then use this color scale for all plots + be able to display the color bar as a legend next to the plot. This sounds trivial, but I can't find useful hints in the documentation of the color arguments of the different plots. Thanks so much for any help Best Marion
fixed color scale for a series of contour plots

You don't tell us which function you use, but fixing the zlim argument in image or related functions should do the trick. M.
