Re: [Matplotlib-users] Multiple Y Axes...

I've run the two-scale demo, but there is a big problem when I zoom into 
it (in the gtk gui): Only one of the 2 scales (the left one) changes.
Is there a way to select/zoom/move the second scale?
I changed the date_demo.py to display 2 stock quotes, but it is actualy 
unusable because of this.
Any help welcome
