The example below will give you some idea where to start.
It uses twin function in axes_grid toolkit.
(also see
http://matplotlib.sourceforge.net/examples/axes_grid/parasite_simple2.html)
You may use twinx or twiny, but you need to make both x and y axis in
sync to each other (maybe using the "xlim_changed" or "ylim_changed"
event).
To change the title position you set_position method (the coordinate
is in normalized axes coordinate). If you need more control, I
recommend to use annotate function.

ax2.xaxis.set_major_locator(locator)
formatter = DateFormatter(r'$%H^h$')
ax2.xaxis.set_major_formatter(formatter)
t = ax1.set_title("Title")
t.set_position((0.5, 1.05))
plt.show()
