How can I lock the colorbar when adding new contour plots?

I am trying to plot multiple matrices using the 'contour' function.  I want the colorbar to be fixed after plotting the first matrix.  How can I do this?

In order to lock the color range after plotting the first matrix, you can use the 'caxis' function.  Execute the following two lines of code after the first plot is made.

C=caxis;

caxis([C(1),C(2)])

The first line of code gets the current limits of the color axis.  The second line of code explicitly sets the limits of the color axis.  Explicitly setting the limits of the color axis should prevent MATLAB from automatically choosing limits on subsequent plots.
