exp.as_pyplot_figure() renders two plots instead of one

[ianozsvald]

Two identical plots are generated, one is expected:

Try using a semicolon. exp.as_pyplot_figure();

[marcotcr]

Yeah, as_pyplot_figure displays and returns the figure, which in turn gets displayed by jupyter if you don't assign it to anything or don't add a semicolon as mentioned above.

Another way to avoid this problem is to use the underscore to ignore the function's return value.

_ = exp.as_pyplot_figure()

I think this is more readble.
