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;
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 colormap limits to a range much larger than the range of values in matrix Z
. The clim
function controls the mapping of data values into the colormap. Use this function to set the colormap limits.
clim([-20,20])
title('Center of Hot Colormap')
Before R2022a, change the colormap limits using caxis([-20 20])
.
