Contours are not removed correctly when using clabel with manual #9988
Description
Bug report
Bug summary
Contours created using pyplot.contour are not correctly removed when labelling the contours usingplt.clabel invoked with inline=True and manual positions.
Code for reproduction
import numpy as np
from matplotlib import pyplot as plt
x = np.linspace(-1, 1)
xx, yy = np.meshgrid(x, x)
fig, axes = plt.subplots(1, 2, True, True)
manual = None
for ax in axes:
cs = ax.contour(x, x, xx ** 2 + yy ** 2)
clabels = plt.clabel(cs, manual=manual)
manual = [label.get_position() for label in clabels]Expected outcome on the left, actual outcome on the right

Thanks for the nice test. Interestingly its backend dependent: MacOS is OK, though different than the outplacement; Qt5Agg is worse than what you show above. I'd try Qt5Cairo, but its not merged yet :-(

Interesting. I'm ultimately interested in rendering to PDF. Do you think using the MacOS backend first and then using
fig.savefig('/path/to.pdf')could do the trick?jklymak commentedon Dec 12, 2017
Oddly that does seem to do the trick. But.... This is still a bug.

... a mercifully one-line bug... See #9989
