Anton, The other thing to bear in mind is that with contourf, you are specifying the data values at grid points, and the algorithm is essentially interpolating to calculate the boundaries of polygons for which the data are between two adjacent contour levels; with pcolor you are specifying the boundaries of a grid, and your data values determine the colors of those rectangles (or more generally, quadrilaterals). That is, with pcolor your data value, Zij, determines the color of the box with corners at Xij,Yij and Xi+1 j+1, Yi+1 j+1.
