Anyone find an answer to this one?  I'm running into this issue with 0.90.1 and I found this in the archives.  I tried the suggested code and it doesn't seem to work for me.  Right now my workaround is

        min_x = min([min(line.get_xdata()) for line in self.axes.lines])
        max_x = max([max(line.get_xdata()) for line in self.axes.lines])           
        self.axes.set_xlim(min_x,max_x)

Any suggestions?

Thanks,
Greg

No way, it doesn't update the axes. Uhm, in my plot I have only lines
and one legend, nothing more. Even if I try a simple case with 2 lines
and I remove one of them, the axes still stay with their previous
limits. I must be missing something.

No problem, as soon as I am able to update the axes, I will add that
info to the wiki.

Thank you.

Andrea.
