525378289,MDExOlB1bGxSZXF1ZXN0NTI1Mzc4Mjg5,4600,closed,0,plot tests: ensure all figures are closed,24938400,"Test `testxyincrease_false_changes_axes` is flaky in nature.

TestCase passes consistently in the actual order with command:
```
pytest tests/test_plot.py
```

TestCase fails when one randomises the order in *test_plot.py* module by using the plugin [pytest-random-order](https://pypi.org/project/pytest-random-order/) with command:
```
pytest tests/test_plot.py --random-order-seed=802425 -v
```

The victim `test_xyincrease_false_changes_axes` fails in a failing test order because there is at least one test that runs before the victim and “pollute” the state (e.g., global state: here, it is `matplotlib's plt`) on which the victim depends. [(Paper)](https://taoxie.cs.illinois.edu/publications/esecfse19-ifixflakies.pdf)

After investigation, we found the polluter test to be *test_ylim_kwarg*

Potential Fix: Adding a `plt.clf` or `plt.cla` at the end of the polluter test. Let us know your preference.

Please let us know if you require the pass and fail logs.

Also, if one runs test_plot.py in any random order, Teardown phase throws an error which is raised by test_all_figures_closed(). 
Should I raise a separate PR for the same?
