Description
If a non-GUI background is being used, and plt.gcf().show() is called it raises the warning
/Users/dstansby/matplotlib/lib/matplotlib/figure.py:402: UserWarning: matplotlib is currently using a non-GUI backend, so cannot show the figure
"matplotlib is currently using a non-GUI backend, "
However, calling plt.show does not raise this warning, and just silently doesn't show anything. I would expect at least the same warning to be raised.
