Hack to show matplotlib plots inline in Calysto Hy jupyter notebooks

[abidsikder]

I was working on some data science notebooks with Hy https://github.com/abidsikder/datascience-hy-notebooks but couldn't get the matplotlib graphs to show inline in the notebook, so I made this hacky function show https://gist.github.com/abidsikder/daad29624665a6ca75b4f20925428493 , you can see it in the data science notebooks e.g.

Looks nice @abidsikder, thanks for sharing! Quite appreciated, since I am using matplotlib more and more these days.

Also seems like something which could be easily added to Calysto_Hy, but that's tricky since the project seems abandoned.
