I didn't understand your question exactly but scatter might be solution for you. You need a x vector y vector and a matrix. Google matlab scatter. I can help better if you have a simple example and if you can elaborate better.

Visualizing a matrix for relative magnitudes can be done with surf or I like imagesc.
A=randi(256,[64 128]);
figure;imagesc(A)
You can threshold and change from color to grayscale.
figure;imagesc(A,[0 192]);colormap gray;axis equal;axis tight
