On Windows, plot() call hangs when plot_is_static=True

[ZmeiGorynych]

In both notebook and PyCharm, when trying to call plot() after fit, the call hangs without producing a plot.
Workaround: call plot(False) to produce an interactive plot; in fact I think False should be the default.
but True should still work as well

replicated with a fresh conda env

conda create -n pizza_test3.9 python=3.9
conda activate pizza_test3.9
pip install wise-pizza
pip install ipykernel fastparquet matplotlib 

Then running a notebook (with internal data) and calling plot() on the object returned by explain_changes_in_average causes the notebook to hang.

Also hangs in the above environment when running the example notebook from the repo

Changed plot_is_static True -> False by default. So now plot() returns dynamic plots. Will return to this issue later.
