[Feature] [Self-assigned] Add heatmap plotter

[DanielYang59]

Hi @janosh, I happen to have some plotting scripts for my MPhil research which includes plotting heatmaps. Shall I proceed and try to merge them into your package?

For example:

And this (I didn't find a good way to fix these overlapping labels though):

Certainly, if you can turn these figures into generic reusable functions and provide the specific outputs above as usage examples in the examples/ folder, that would be great! 👍

[DanielYang59]

@janosh Sure thanks. I would look into your existing codes and try to unify the function input/output flow. Cheers!

[janosh]

Happy to help. Feel free to open a PR early and we can iterate together.

@janosh Thanks for offering that. However I might prefer to take my time and format the code on my own pace for the time being. I mean no offence but your energy is crazy, there is no way for me to catch up haha... Also coding is quite new to me (around only ~1 year experience) plus I'm current busy cleaning up my Journal Paper from my previous MPhil Thesis to support my future PhD position searching.
