[Matplotlib-devel] Getting MultiCursor Subplots values (coordinates)

[Thomas Caswell]

It looks like MultiCursor does not directly store that information, it just
implicitly stores it in the positions of the lines.  I would look at
`multi.vlines` and `multi.hlines`, loop over those and extract the
information you need.
