Samuel,

Trying to manipulate variables with leading underscores is 
discouraged--that is the meaning of the leading underscores.

Changing the shared status of axes involves changes in additional 
variables.  This could be encapsulated in a single method.  It might be 
very easy, or complexities and gotchas might turn up. How important is 
it?  What is the problem with setting the shared status when you make 
the axes, as in your first example?

Hello,
I am writing a little GUI with PyQT4 and matplotlib.
So it is embeded.
I want that feature for the user : he can decided after ploting some
data to synchronize 2 graph with the x axis for the zoom.

So this method would be very useful for me. Maybe I can write it.
Do you have a idea of all the variables involved in the sharex feature ?

Thank you

Samuel

It doesn't look too easy, without some additional methods in the BBox
extension code.  I'll look into it.
