I wanna change the scale of the color bar. of the image below to [0 0.02]
I tried many method, like shown below
image(x,y,D')
c = colorbar;
%c.Limits = [0 0.02]
%set(c,'ylim',[0 0.02])
but the outcome is like this. The colorbar become the same color. only the range changes instead of the scale. I want the colorbar to be different from 0 to 0.02. How should I do that? Thanks for answering!

you can use the caxis command, simply add caxis( [0 0.02]) below the colorbar command.
figure
surf(rand(10,10))
c = colorbar;
caxis([0 0.2])
