Re: [matplotlib-devel] Heatmap for 7K X 7K matrix

[Jens N. <jen...@gm...>]

Hi Madhav

We have moved our mailing lists off source forge to python.org I recommend
that you use one of the mailing lists here see the readme
https://github.com/matplotlib/matplotlib/blob/master/README.rst this type
of question is probably most suited for the user list rather than the
developer list.

Did you recently find a link to the old one? In which case we would like to
know where so we can update the reference.

Back to your question, If I understand correctly I think what you are
looking for is a data cursor that can show you information when you click
on a specific point.

https://pypi.python.org/pypi/mpldatacursor/ is one such package.

Best Jens
