The negatives look dark blue even at low magnitude. I think the function must make the max and min data values the darkest color end points. I tried to force the negative data to show up lighter blue by using caxis to limit the colors from -0.5 to +0.5 but then zero is not white for some reason.Change the colormap*: colormap(jet) Add a colorbar and put a label on it: cb = colorbar; ylabel(cb,'voltage') Set colorbar limits: caxis( [-8 4]) That'll create this figure: * But note, there are some perceptual issues with using jet to represent numbers.

exactly. The created colorbar is an individual object on the figure and will not change no matter what you do with you subplots. In order to change that you would have to add a listener to the colorbar that will recalculate on colormap changes within the subplots.
