Change Fill Colors for Contour Plot

This example shows how to change the colors used in a filled contour plot.

Change Colormap

Set the colors for the filled contour plot by changing the colormap. Pass the predefined colormap name, hot, to the colormap function.

[X,Y,Z] = peaks;
title('Hot Colormap')

Control Mapping of Data Values to Colormap

Use only the colors in the center of the hot colormap by setting the color axis scaling to a range much larger than the range of values in matrix Z. The caxis function controls the mapping of data values into the colormap. Use this function to set the color axis scaling.
