Description
Bug summary
Reopening #441 since the fix seems not to work on two corner cases:
- Clockwise direction with
set_theta_direction(-1)
- Angle offset set by
set_theta_offset(np.pi/2)
Code for reproduction
from numpy import *
from matplotlib import pyplot as py
r = zeros([16])
err = zeros([16])
for i in range(16):
r[i] = random.randint(400, 600)
err[i] = random.randint(20, 50)
theta = arange(0, 2 * pi, 2 * pi / 16)
width = pi * 2 / 16
fig = py.figure(figsize=(8, 8))
ax = fig.add_axes([0.1, 0.1, 0.75, 0.79], polar=True)
bars = ax.bar(
theta + pi / 16,
r,
width=width,
bottom=0.0,
yerr=err,
capsize=15 # Capsize set to exaggerate issue
)
ax.set_ylim(0, 700)
ax.set_theta_direction(-1) # Clockwise direction
py.show()

Actual outcome
Expected outcome
Errorbar caps perpendicular to the error bars.
