Re: [Matplotlib-users] Autoscale embedding in gtk + dynamical update of plot + Y log scale

[Sandro T. <mo...@de...>]

Hi All,
I'd like to renew this request below.

I've worked-around this problem setting xlim/ylim (as min/max of the
relative axis) right before redraw the figure, but I'd like to know
for a more elegant solution.

Thanks in advance,
Sandro
