Default toolbar overlaps figure

L’issue riguarda il comportamento di toolbar_position nell’integrazione di Jupyter Notebook; inizia individuando l’implementazione che posiziona la barra degli strumenti predefinita e tutti i test di layout correlati. Riproduci la sovrapposizione con constrained_layout=True, quindi verifica che la barra degli strumenti e la figura occupino riquadri separati per il comportamento di posizionamento scelto.

Describe the issue

The default position of the toolbar is on the left, where it overlaps the figure.
Especially when the constrained_layout=True keyword is used when creating the figure,
this is highly undesirable.

Possible solutions or workarounds:

• Minimal fix: Change the default to anything other then "left"; I think that with the current design, "right" would be by far the best. It would minimize the likelihood of an overlap.
• The real fix: When the toolbar_position is on the left, position the figure to its right. Ideally, all toolbar positions should be in boxes that never overlap the figure box. With this scheme I suggest putting the default toolbar on the top or bottom, and flush left, to match all of the other matplotlib interactive backends.
