Excessive white space / margins with some plots.

With the current ipympl 0.9.6 (and probably earlier versions) I am observing excessive white space around axes in some cases when using the %matplotlib ipympl mode but not in the %matplotlib inline mode.

A small example to reproduce:

%matplotlib ipympl
from matplotlib import pyplot as plt

fig, ax = plt.subplots(figsize=(5, 3), constrained_layout=True)
ax.imshow([[1,2,3],[4,5,6],[7,8,9]])
ax.set_aspect(0.1)

This yields:

And the same example in inline mode:

%matplotlib inline
from matplotlib import pyplot as plt

fig, ax = plt.subplots(figsize=(5, 3), constrained_layout=True)
ax.imshow([[1,2,3],[4,5,6],[7,8,9]])
ax.set_aspect(0.1)

Especially larger figures then became unmanageable in the ipympl backend. Setting constrained_layout or using plt.tight_layout() does not seem to influence the margins. Can this behavior be influenced?

Commencez par exécuter les deux exemples fournis avec %matplotlib ipympl et %matplotlib inline, en incluant les paramètres de constrained layout et aspect. Comparez les marges obtenues et retracez le comportement du rendu et de la mise en page de la figure ipympl. Le travail est terminé lorsque l’exemple ipympl ne produit plus d’espace blanc excessif autour des axes, y compris pour les figures plus grandes.
