Github seems to be having trouble updating the website at the moment.

Courtesy of Matthew Brett, we now have Mac OS X installers again. These 
are designed to work with the python.org distribution, and include all 
dependencies.
They are available here:
http://matplotlib.org/downloads
Please let us know how you fare!

There was a pull request that was put together about 6 months ago that I
think fixed the problem, IIRC, but it broke the API and the submitter
eventually retracted the PR because it didn't seem like the right solution.
The problem is extremely nuanced and there is no clear solution,
unfortunately. The general idea is that the path codes are not being stored
with the vertices because the underlying object holding that data is a Path
(so the 3D vertices are stored separately, and as such, the list of
vertices diverges from the list of path codes). Perhaps, if there was a way
to make Path objects be able to hold 3D vertices, we might be able to solve
this issue once and for all?

Hi,
I have exactly the same problem described here. Is there any solution to 
turn off the baseline in the polycollection?
Cheers,
Guido

Hi Joe,
Just now I installed your package mpldatacursor and run the example
image_example.py.
Awesome !
Is there a chance to integrate it into matplotlib ?
