In this example, though, he is not adding the Circle to the Axes via add_patch (so the transData transform is not set). Rather, he is using it to set the clip path http://matplotlib.sourceforge.net/examples/api/clippath_demo.html So I think Ryan's answer is correct. But David, if you want the clippath to be in data coordinates, you can set the transform yourself patch = patches.Circle((300,300), radius=100, transform=ax.transData) See the transformations tutorial for more about the coordinate systems and transformations http://matplotlib.sourceforge.net/users/transforms_tutorial.html JDH ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
