I have a graph with multiple point. I want to change color when 2 points are superimposed. By exemple, when 2 points are superimposed, the color of the resulting is pale blue. 3 points at same place, color is blue, 5 points yellow, 10=red etc.
with few points it would be easy to make a loop to check but I have a 64 X 120 matrix (y-axis) and a vector X 64
Thank

Just plot the sum of y horizontally vs. x.

Well maybe I'm thinking of your array wrong then. Why don't you first read this and then give a small example to show what the x and y values are and what colors you think they should be?
