Matplotlib equivalent of pygame flip

Question

I have a program with rapid animations which works perfectly under pygame, and for technical reasons, I need to do the same using only matplotlib or an other widespread modu

Answer 1

If you want to animate a plot, then you can take a look at the animation functionality in matplotlib under matplotlib.animation.Animation. Here's a great tutorial - https://jakevdp.github.io/blog/2012/08/18/matplotlib-animation-tutorial.

If you just want to periodically update an adhoc bitmap, I am not sure matplotlib is meant for what you are trying to achieve. From matplotlib docs:

Matplotlib is a Python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms.

If you would like to periodically update an adhoc image on the screen, you may want to look into GUI libraries for python. Here is a short summary of available options - https://docs.python.org/3/faq/gui.html. Tkinter is a pretty standard one and is shipped with python. You can use the ImageTk module in pillow to create/modify images for displaying via Tkinter - http://pillow.readthedocs.io/en/4.2.x/reference/ImageTk.html.
