• I have checked that the issue still exists on the latest versions of the docs on master here

Documentation problem

When following the tutorial, plot may not appear, depending on the environment. Some environments require plot.show, some will require plot.savefig.
PR #43544 adds a very brief explanation.

Suggested fix for documentation

If running under Jupyter Notebook, the plot will appear on ~ts.plot. Otherwise use matplotlib.pyplot.show to show it or matplotlib.pyplot.savefig to write it to a file.

plt.show();
