1. The problem statement, all variables and given/known data Hello, I'm given three (one-dimensional) arrays, names x, y & p. I want to draw a map, where p determines the color, and (x, y) are the coordinates. 3. The attempt at a solution Usually I would use contourf, but here x & y are distributed quite randomly on the plane, so I can't create them matrices with meshgrid (I tried just filling matrices with these arrays, and the result is horrible). I.e. The problem is that those are array that I should map and not matrices. Thanks in advance!
