How can I associate a colour to a coordinate depending on the family of its highest associated value ?
For example, if my coordinates are X=[2 4 -3 5 6] and Y=[4 9 1 -2 1] and my associated values are L1 (blue) =[1 1 1 1 1], L2 (green) =[2 1 2 1 2], L3 (red) =[3 3 3 3 1] and L4 (purple) =[10 0 2 0 0], I want the coordinate (2,4) to be purple, the coordinate (4,9) to be red, the coordinate (-3 1) to be red and so on.
The main objective is to make a "phase diagram" that tell us which treatment between L1, L2, L3 and L4 is the most optimal (has the highest value) for each point in space.
