%% Change Color Axis Scaling % Define |X|, |Y|, and |Z| as data for a sphere and view the data as a % surface. Define the colors for the surface, |C|. % Copyright 2015 The MathWorks, Inc. [X,Y,Z] = sphere; C = Z; surf(X,Y,Z,C) %% % Values of |C| are in the range |[-1,1]|. Values of |C| near -1 are % assigned the lowest values in the colormap. Values of |C| near 1 are % assigned the highest values in the colormap. % % Map the top half of the surface to the highest value in the color table % by setting the maximum color limit to 0. caxis([-1,0]) %% % Reset the axis scaling back to its default range. caxis auto %% % Return the values of the current color limits. v = caxis
