matplotlib.pyplot.ion() does not work very well about pythonqt HOT 3 OPEN

Thanks for reporting the problem.

This is most likely explained by the fact plt.draw() creates its own event loop.

An approach would be to subclass an existing matplotlib backend.

While PyQt is different from PythonQt, here are some hints that should apply:

Related docs:

May be you could try:

plt.show(block=False)

from pythonqt.

Hello,

following the advice on that topic, I hit a few bugs but I managed to get a working backend to integrated matplotlib in PythonQt. At its current stage, it is probably not perfect. I have two questions:

• would you be interested in including this backend in the package ?
• If yes, is a draft version fine ?

The code can be found on branch matplotlib of my fork: https://github.com/jmirabel/PythonQt/tree/matplotlib (based on branch patched-6 of this fork).
