You can force axes in the same figure to share the same xaxes

ax1 = subplot(211)
ax2 = subplot(212, sharex=ax1)

then any changes (panning and zooming) in one will be instantaneously
reflected in the other.

For axes in different figures, you can set the xlim manually

ax1.set_xlim(xmin, xmax)
ax2.set_xlim(xmin, xmax)

There is more sophisticated stuff you can do with observers and event
handling to couple axes between figures in the presence of panning and
zooming if need be.
