Try either: plt.matshow(zi,cmap=plt.cm.hot) or plt.imshow(zi,cmap=plt.cm.hot) The first should be the quickest - it doesn't do any fancy interpolation, and actually just passes some arguments to the second. Using imshow directly, however, allows you to set a different type of interpolation, should you desire it. If you want xi and yi to be accurately reflect in the plot, you might have to play around with changing the axis formatters (though there might be an easier way of doing that, which escapes me right now) best, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7
