Bug summary
I trying to run my 1-year-old polar plot (made with matplotlib 2.0.0) but with current 2.2.2 version get "posx and posy should be finite values" error. I found out that the error is caused by the ax.set_ylim() method. Such way to manage the axis I've got from this SO question/answer. So this case looks like broken compatibility with older scripts.
Code for reproduction
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure(dpi=120)
ax = fig.add_axes([0.1, 0.1, 0.8, 0.8], polar=True)
ax.set_theta_zero_location('N')
ax.set_theta_direction(-1) # anti-clockwise
ax.set_ylim(90, -45)
ax.set_yticks(np.arange(-45, 90+0.1, 15))
plt.show()Actual outcome
