Add "blit=False" in the instantiation for multicursor to get around the
copy_from_bbox issue.
I wonder if the use of fig.axes might be a problem?

HI all,
I wanted to help (for a change) but running the script on mac (with the multi cursor code commented out), I got the following error. If anyone can figure out why !
File "/Users/j35/anaconda/lib/python3.4/site-packages/matplotlib/widgets.py", line 1046, in clear
 self.canvas.copy_from_bbox(self.canvas.figure.bbox))
AttributeError: 'FigureCanvasMac' object has no attribute ‘copy_from_bbox'
I’m using python 3.4 and matplotlib 1.4.3
Thanks
Jean

Hi Gurus:
I'm having a serious problem with MultiCursor and autoscaling...
If I do the code below with both MultiCursor instantiations commented 
out, then all plots are xscaled to [50,55] and yscaled to each plot's 
appropriate ylimits.
If I uncomment the top MultiCursor instantiation, then both the xlimits 
and ylimits are screwed up: xlim=[0,60] and ylim is all over the place, 
certainly not autoscaled tight.
If I uncomment the bottom MultiCursor instantiation, then the xlimit 
appears to be scaled correctly, [50,55], but two of the four plots 
(lower left and upper right) are not autoscaled in y.
How to I instantiate MultiCursor to get the normal and expected 
autoscaling behavior?
Not that it should matter, but I'm using here Tk and Python3 with MPL 
1.5dev1 (91ca2a3724ae91d28d97)
Thanks for any help,
M
