Problem
Calling art.remove() doesn't seem to completely detach the art from the original axes.
In the following sample code, when removing the art from axes (say ax1) and adding it to other axes (say ax2), the ax2 will not draw the art.
import numpy as np
from matplotlib import patches
from matplotlib import pyplot as plt
data = np.random.rand(5,5)
fig = plt.figure()
ax1, ax2 = fig.subplots(1,2)
ax1.imshow(data, interpolation='nearest', cmap='gray',)
ax2.imshow(data, interpolation='bilinear', cmap='gray',)
if 1:
art = patches.Circle((2, 2), 2, fill=0)
ax1.add_artist(art)
art.remove()
ax2.add_artist(art)
plt.show()This issue was raised on: Discrouse matplotlib.
Proposed solution
The following line is suggested to be added after `art.remove()':
art.set_transform(ax2.transData)
or
art._transformSet = False
should be added in the art.remove method.
