In general, yes, you should avoid using pyplot when embedding. However,

embedding the matplotlib's canvas into your own instantiated Window object.
If you are embedding GUI elements into a matplotlib figure window, you
actually can still utilize pyplot (but very carefully).

I suggest reading up my book:
