How to assign a different colour for each layer?

Hi everyone,

I am Luca and I have performed an atomistic simulation of epitaxial growth. I have written a specific code for atoms deposition. My result is the following one:

As you can see, this color grading isn't acpetable in order to recognize different layers. How should I do in order to assign a different colour to each layer in order to get a result like the one below?

Thank You!

Assuming you're using bar3()

% make some example data
maxlayers = 5;
z = randi(maxlayers,10,10);

h = bar3(z); % the plot

% make a discrete colormap
colormap(jet(maxlayers));
% set cdata to zdata
for k = 1:numel(h)
    h(k).CData = h(k).ZData;
    h(k).FaceColor = 'interp';
end
% offset clim just a bit to keep tops colored right
caxis([0 maxlayers]+0.001)

Everything works, Thank you!
