Bug summary

With 3.5 and previously, doing hexbin with empty arrays and log scaling just produced an empty plot. With 3.6.0 it crashes.

Code for reproduction

import matplotlib.pyplot as plt

plt.hexbin([], [], bins='log')

Actual outcome

...

File ~/miniforge3/envs/mpl36/lib/python3.10/site-packages/numpy/core/_methods.py:44, in _amin(a, axis, out, keepdims, initial, where)
42 def _amin(a, axis=None, out=None, keepdims=False,
43 initial=_NoValue, where=True):
---> 44 return umr_minimum(a, axis, None, out, keepdims, initial, where)

ValueError: zero-size array to reduction operation minimum which has no identity

Expected outcome

It just runs and then a plt.show() gives an empty rectangle.
