Bug report
On master branch, plotting datetimes appears to be broken. This error bisects to a793bde in #17022
Code for reproduction
import matplotlib.pyplot as plt
from datetime import datetime
fig, ax = plt.subplots()
ax.plot(datetime.now(), 1)
plt.show()Actual outcome
File "test.py", line 5, in <module>
ax.plot(datetime.now(), 1)
