[Matplotlib-users] Pick PathCollection component by interior

[Brendan B. <bre...@br...>]

	I have a PathCollection with a lot of closed paths.  I'm trying to 
implement a "data cursor" as described here: 
http://stackoverflow.com/questions/4652439/is-there-a-matplotlib-equivalent-of-matlabs-datacursormode 
.  I've done this successfuly in the past when the objects I wanted to 
pick were points.  However, with this PathCollection, I want to be 
able to click inside the region enclosed by a path, and select the 
path that encloses that region.  Using the basic sort of code as shown 
in that post, it seems to only select the path when you click on the 
path itself --- that is, the boundary of the region.

	How can I get a pick event for a PathCollection that tells me the 
path whose interior I clicked in?  To make things even more 
complicated, some of the paths are not simply-connected and contain 
other paths inside their "holes", but even handling it without that 
wrinkle would be a start.

Thanks,
