%% 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. % Copyright 2015 The MathWorks, Inc. [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 |Z|. The |caxis| function controls the mapping of % data values into the colormap. Use this function to set the color axis % scaling. caxis([-20,20]) title('Center of Hot Colormap')
