Heatmap for 7K X 7K matrix

Sending again after joining list

Hi matplotlib users,

I am trying to generate a fairly huge heatmap of a 7000 X 7000. This is a 2D matrix in which each cell i,j have a similarity score between ith and jth label.

PFA my first attempt (code - [0]).

Now I am looking for better visualization which can also tell me more about cell level information. To start with can I create a higher resolution image such that I have at least 2X2 pixel for every cell. Resultant should be of resolution 14000 X 14000

Are there more features like- By some user interaction can I know what pair it represent? and what’s the similarity score?

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.

Madhav,

Do I understand correctly that you want to generate a 14k x 14k image in matplotlib? Are there computer monitors available that can display such an image in native quality?
