PR Summary

EngFormatter was not respecting the axes.unicode_minus rcParam.

Example (old behavior)

import matplotlib.pyplot as plt
from matplotlib.ticker import EngFormatter
plt.rc('font', size=14)
fig, ax = plt.subplots(figsize=(4.0, 2.5), constrained_layout=True)
ax.plot([-10000, -5000, 0, 5000, 10000], [-10000, -5000, 0, 5000, 10000], '*-')
formatter = EngFormatter()
ax.xaxis.set_major_formatter(formatter)
ax.yaxis.set_major_formatter(formatter)
fig.savefig('old_EngFormatter.png', dpi=200)

Example (New behavior)

PR Checklist

  • Has Pytest style unit tests
  • Code is Flake 8 compliant
  • New features are documented, with examples if plot related
  • Documentation is sphinx and numpydoc compliant
  • Added an entry to doc/users/next_whats_new/ if major new feature (follow instructions in README.rst there)
  • Documented in doc/api/api_changes.rst if API changed in a backward-incompatible way

working on updating the failing tests to ensure both cases (with and without unicode minus) are checked (current tests don't include unicode minus).

Updated the test to make it pass. Should I be checking for the non-default value of the rcParam axes.unicode_minus=False? The current test assumes the default value of the rcParam axes.unicode_minus=True.

rcparams are always reset to their defaults before running the tests.

I guess adding a test that things work as expected when the rcParam is changed before creating the formatter would be nice, but not compulsory.

Updated the test to check for the non-default value of axes.unicode_minus rcParam. I think this is ready for review.

Remilestoning to 3.1. It's good to get this in.

Thanks! I was going to request that. I wasn't sure about the workload on core developers so was hesitant.
