When creating a polar plot with inverted theta direction and modifying the location of zero, the radial grid and outer boundary are missing for some locations of zero.
import numpy as np
import matplotlib.pyplot as plt
r = np.arange(0, 2, 0.01)
theta = 2 * np.pi * r
fig, ax = plt.subplots(subplot_kw={'projection': 'polar'})
ax.plot(theta, r)
ax.set_theta_direction(-1)
angle = 10 # 20 is not working, 10 is working
ax.set_theta_zero_location("N",angle)
plt.savefig('expected-outcome.png')
angle = 20 # 20 is not working, 10 is working
ax.set_theta_zero_location("N",angle)
plt.savefig('actual-outcome.png')This is the outcome (can be reproduced with angle=20):
And this is what it should look like (can be reproduced with angle=10):
import matplotlib
print(matplotlib.__version__)
import platform
print(platform.python_version())
3.4.2
3.9.2
When I go back to matplotlib release v3.2.2 I don't have this issue.
