max open warning

See original GitHub issue

Hi, I use ipympl in jupyterlab.%matplotlib widget opens a different figure for the same cell after each run. Soon I’ll get this max open warning, which is kinda irritating. %matplotlib notebook has no such issue. Is there a way to not open another figure in the same cell?

Hi all, just checking if there are any updates on this. I’m a daily user, and I agree with Merlin that it is pretty irritating.

plt.close('all') will also close all open figures.

I think the underlying problem here is that with nbagg when the js-widget is removed from the DOM we tear down the figure on the pyplot side and (try) to release all of the references, however with ipympl because the widget may be shown in multiple contexts.

There needs to be some reference counting to tell when there are no visible figures left?
