Heheh, Did you try that? (Mathematica colors the background of the second plot white, so showing them both overwrites the contours of the first plot with white. It is still an interesting approach. I am sure the relevant graphics directives could be reaped out of the second plot. The main difficulty with this approach would be that the contour shading might be off (ie, some inner rings might be lighter than some outer rings). I wonder if that could be circumvented by extracting the PlotRange from the AbsoluteOptions of the first graph and setting that as an option for the second. I will look at this approach some more. Thank you Mr. Rowe.
