matplotlib issue with polar plot after 2.0.2

Question

Releases of matplotlib after 2.0.2 cause the polar plot to be drawn incorrectly. The top of the green plot goes missing. None of the input data has been changed between versions.

Version 2.1.0

Version 2.0.2 (good)

import matplotlib.pyplot as plt

theta_radians = np.radians(theta)
fig = plt.figure()
ax = fig.add_subplot(111, polar=True)
ax.set_theta_zero_location("S")
ax.plot(theta_radians, r, color='green')
ax.plot(np.dot(theta_radians, -1), r, color='green')
ax.plot(horiz, arr[25, :])
fig.savefig('./filename.png', dpi=300)
fig.show()

Answer 1

The issue seems to be in the way it sets the bottom limit. I managed to resolve this using:

ax.set_rlim(0,max)

Fixed Example Version 3.0.2
