Set the colors for the filled contour plot by changing the colormap. Pass the predefined colormap name,
hot, to the
[X,Y,Z] = peaks; figure contourf(X,Y,Z,20) colormap(hot) 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
caxis function controls the mapping of data values into the colormap. Use this function to set the color axis scaling.
