title: How to readjust caxis on all subplots?
body: <p>So I have two subplots with different caxis values. Is there a way to use caxis([-2 2]) so that it could rescale the caxis for all of the subplots? There is a single function that produces each plot, and I want all of the plots to have the same caxis to facilitate comparison.</p>
