Colormap limits between 0 and 1

Below I have a small code which outputs an image from a simulation. The image I get will have an arbitrary axis for intensity, which I would love to have scaled to be between values of 0 and 1.

How can I achieve this?

Ex = reshape(csvread('gif240psex.td2', 23), 101, 101, []);
Ey = reshape(csvread('gif240psey.td2', 23), 101, 101, []);
pcolor(mean(abs(Ex).^2 + abs(Ey).^2, 3))
shading interp
title('VCSEL Intensity Graph')
xlabel('x-Length (μm)')
ylabel('y-Length (μm)')
colormap(jet)
colorbar

I think you have to rescale the plotted quantity. That is:

val = mean(abs(Ex).^2 + abs(Ey).^2, 3);

val = val / max(val(:));

pcolor(val);

If it doesn't work, share your data so mi or someone else can check where is the problem.

Hi Riccardo,

That suggestion worked perfectly, thank you so much!
