[Matplotlib-users] Double zooming with twinx

[Paul S. <pau...@ca...>]

I'm plotting two curves in one subplot with twinx to allow different y scales. 
The script below is an example. 
When zooming in using zoom-to-rect on Tk's navigation toolbar2 (TkAgg is my 
backend) I think the x axis part of the zoom is happening twice. Rubberbanding 
the example from x=20 to 80 results in a zoomed x range of about 32 to 68, 
which is about what you'd expect for zooming with the same range twice. 

Is there a way of restricting this to only one zoom?

from pylab import *
f=figure(1)
ax1=f.add_subplot(111)
ax1.plot(arange(100))
ax2=twinx(ax1)
ax2.plot(-arange(100),'g')
draw()
