Compound paths

Are there any more examples of matplotlib's new path functionality, in addition to the one in examples/api/path_patch_demo.py? Specifically, I would like an example of using compound paths to draw a donut-shape that shows the inner and outer edge and fills the donut with a color.

Thank you,
Paul

I'm always glad to see that old chestnut resurface, but it doesn't really address the need for a hole in the middle. (I'm sure the dolphins are very happy about that...)

matplotlib paths use the "non-zero" filling rule, so the directionality of the path affects filling. The best concise description I know of is here:

http://www.w3.org/TR/SVG/painting.html#FillProperties

So the direction of the inside and outside paths must be different in order to create donut-like shapes.

I've added donut_demo.py to the examples (add attached it here).

Hope that helps.

Cheers,
Mike
