plt.close() vs plt.show()

[AdamRJensen]

You shouldn't start a new plot by using plt.close()

If anything you can use plt.show() at the end of a plot which avoids showing the output line (shown in yellow below):

Please remove all instances of plt.close() in the documentation.

Thanks Adam. The use of plt.close() throughout is vestigial and habitual from my usual use of %matplotlib widget outside of training notebooks. Unfortunately necessary for my usual use cases until matplotlib/ipympl#4 gets resolved! All fixed up now.
