Hello, Now I don't understand. Inline

why are you writing ncol=2 ? I have levels=100 for x1 and the x1 is my z matrix
In your contour instruction x3 is the z matrix, not x1. And your dataset shows a 2x3 grid, hence ncol=2, for (x1 times x2) 0:1x1:3.
Also, see Eik's post, lattic graphics clearly are more intuitive. Rui Barradas
