disc2 + disc1 you will see some of what is going on. If you change disc1= region_plot(lambda x, y : x^2+y^2 < 1, (x, -1, 1), (y, -1, 1), incol='red', outcol='orange') you will really start having fun :) I hadn't seen the plots yet when I said zorder - this is more of a cancellation thing going on with two uses of matplotlib and will take a little more thought, because probably we are somewhat abusing things by using contourf twice in the same subplot. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
