For the following code, if I remove the transform=None a green patch is
shown. If it is in, it is not shown. I would think that transform=None
should have no effect. Why is this?
Thanks,
Che
import matplotlib.pyplot as plt
import matplotlib.patches as patches
from matplotlib.path import Path
fig = plt.figure()
ax = fig.add_subplot(111)
start = 0.2
stop = .6
verts = [
(start, .2), # left, bottom
(start, .4), # left, top
(stop, .4), # right, top
(stop, .2), # right, bottom
(0., 0.), # ignored
]
codes = [Path.MOVETO,
Path.LINETO,
Path.LINETO,
Path.LINETO,
Path.CLOSEPOLY,
]
path = Path(verts, codes)
patch = patches.PathPatch(path, facecolor='g',
lw=1, edgecolor='grey',transform=None )
ax.add_patch(patch)
plt.show()
