I can confirm the issue with 1.2.1 but it works with a recent
development version (output attached) so it must have been fixed at
some point.

The problem is when to call pyplot.close(fig). The actual visible figure 
on the canvas is often resized along with window it is in, in addition 
to being interacted with in other ways. In these cases you can't just 
close the figure after drawing it - if you do, the resizing results in a 
blank canvas and a PyDeadObjectError.
The easiest workaround to the problem is simply making the whole window 
modal, and closing the figure if the window is closed for any reason - 
or before you create a new figure. This is less than ideal, but lets the 
life go on in this case.

Hello,
I set the x data only once now. It is a little bit faster (about 10%).
I'm still looking for a solution which only redraws the line and not the
whole widget.

Can you confirm the example was good enough for identifying the problem or
did I forget something again?
