As he said, increasing the number of vertices could be enough, depending on your exact needs. If you zoom in on polygons, you will of course eventually see the difference. > May I ask how to create a circleCollection as Jouni "The Expert" > proposed? I meant that you could read through collections.py and implement a CircleCollection along the lines of the other collections there. I'm not quite sure what exactly this entails [so I'm not expert enough to answer your question :-)]. At least it would mean a new method for backends, although one that you could implement once in backend_bases. (Now that I look at collections.py, the base class Collection has a get_verts method that derived classes should override and that other parts of matplotlib call, so perhaps collections of non-polygons would require more extensive changes than just adding a new subclass.) The advantage would be speed of rendering in case you draw lots of circles, so if speed is not a problem, don't worry about this. -- Jouni K.
