A minor clarification: The classic Jupyter notebook has built-in support for live matplotlib interaction through the %matplotlib notebook magic command, but this matplotlib backend does not work in JupyterLab. The ipympl package provides %matplotlib widget which works with both versions of Jupyter.

Moving this ticket to 9.4, as it seems unlikely that it will be merged in 9.3, which is in the release candidate stage
