Color "Thermometer" for different shaded functions

Hi
I have a page of subplots each of which contains a function (a distribution to be more precise). Now each function has a different shade of color according to a certain property. Lets say the more a distribution diverges from a normal the more redish it becomes. What I want to plot next to these subplots now is sort of a thermometer with this color progression where it would be marked at the start of this thermometer "lowest divergence from normal" and at the end "highest convergence ..." etc. Of course it should not look like a real thermometer - how could I do that?
Thanks

You could use one of the built-in colormaps, such as jet, hot, winter, etc. to get your color:
% Create a color map.
thePlotsColorMap = jet(256);
% Calculate your "temperature"
theTemp = whatever....
% Normalize it to 1-256.
colorMapIndex = 256 * (theTemp - minTemp) / (maxTemp - minTemp);
% Get this particular color out of the color map.
colorToPlotWith = jet(colorMapIndex);
% Now call plot with the 'Color' option set to this
plot(x, y, 'Color', colorToPlotWith);

I don't want your code, just the screenshots. http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers
