I've run across a strange problem and perhaps I'm misusing something. I was
trying to set up picking so that I can interact with plotted objects, and I
get alot of error spew that looks like this:
while checking <class 'matplotlib.lines.Line2D'>
Traceback (most recent call last):
File "C:\Python26\lib\site-packages\matplotlib\artist.py", line 241, in
hitlist
hascursor,info = self.contains(event)
File "C:\Python26\lib\site-packages\matplotlib\lines.py", line 286, in
contains
path, affine = self._transformed_path.get_transformed_path_and_affine()
AttributeError: 'NoneType' object has no attribute
'get_transformed_path_and_affine'
This can be reproduced by the following code, even though there is no
picking involved...just mouse motion. Is there possibly a workaround for
this, or am I doing something wrong?
import sys
from pylab import *
ax = subplot(111)
ax.plot([0,1,2,3])
def on_move(event):
if event.inaxes:
lst = ax.hitlist(event)
print lst
binding_id = connect('motion_notify_event', on_move)
show()
