Improve the data clearing experience #16

Closed janfreyberg closed 4 years ago

janfreyberg commented 4 years ago

This makes two changes:

the init_emptydata method lost its prefix ''
the 'clear' method on canvases now also calls init_empty_data

This fixes #15.

Unrelated change: the canvas was being stretched when the notebook cell output container was wider than the canvas. The size of the widget container is now fixed to the size of the canvas.
