Hello, I have a gui in which I display a 2D image and an associated colorbar. When I change the limits of the colorbar, the color range still only goes from 0 to 1, even if I use the limits e.g. -4 to 5 (see attached image for an example). Note that the image is displayed correctly, i.e. within the right range. The colorbar is not however. In the gui, I have an empty axes object called axesColorbar.
handles.colorbar = colorbar(handles.axesColorbar);
set( handles.colorbar, 'Limits',[-1.5 4.5] );
colormap(Jet);
Does anyone know how to fix this? Thank you! Sincerely, Ida

Changing the colorbar limits does not affect the data in the graph.
Either what is being drawn has limits 0 to 1, or else caxis is set to 0 to 1 for the axes.
