Thread: [Matplotlib-users] synchronize magnification of subplots?

I have 2 subplots, 2 rows 1 col.  They have the same x-axis.

I'd like to be able to zoom in on both plots together.  Using qt4agg, there is a 
zoom icon, but it seems to operated on each subplot separately.

I only have the notebook to mes around in, but the following works for me:

%matplotlib nbagg
import matplotlib.pyplot as plt

fig, ax = plt.subplots(nrows=2, sharex=True, sharey=True)

You can also use (

ax2 = subplot(212, sharex=ax1)
