Hi,
Sorry, if this has been brought up before, but I missed a while reading
the list.
When I updated my system lately, I also installed the current version of
mpl (0.90.1) and that gave me a DeprecationWarning that I should use
LineCollection now to get my horizontal lines. Well, I didn't figure out
how to do that until now.
(NB I have an own wxpython app which makes heavy use of mpl and mostly
uses subplot instances.)
Well, this code snippet
from pylab import *
from matplotlib.collections import LineCollection
x = subplot(211)
x.add_collection(LineCollection([(0,0)]))
gives the following Traceback:
Exception in Tkinter callback
Traceback (most recent call last):
File "lib-tk/Tkinter.py", line 1406, in __call__

line 700, in draw

TypeError: CXX : Error creating object of type

The traceback is independent of the backend used, same for wxagg at
least.
Guess, I'm missing something stupid. Can somebody enlighten me?
Thanks,
Christian
