Re: [Matplotlib-users] how do I get my axis

[Mathew Y. <my...@jp...>]

Thanks Angus. I tried this out ... it works once and only once!
BTW, The correct thing to do is
res=fig.gca()
res.fmt_xdata=foo() #instead of format_xdata
res.fmt_ydata=foo()

although, like I said, it only first for the first event. Somehow 
res.fmt_xdata is getting set back to None
