Hi Nils,
I'm glad you found it useful!
I'm certainly not opposed to seeing it integrated into matplotlib in the
long run. At the moment, though, it's probably changing a bit too
quickly. There's a lot of little things I'd like to add to it.
On the other hand, if it ever were integrated upstream, there's an
opportunity to clean things up quite a bit, as mpldatacursor currently has
quite a few workarounds for minor bugs in old versions of mpl and minor api
changes, etc.
Cheers!
-Joe

Android is increasing in popularity, but the open development platform that
developers love is also attractive to malware creators. Download this white
paper to learn more about secure code signing practices that can help keep
Android apps secure.
