I wonder why the simple text command does not work for you? e.g.,
def add_center_text(ax):
ax.text(0.5, 0.9075, "Centered Title", ha='center', va='center',
fontsize=18,
bbox=dict(boxstyle='round, pad=0.5, rounding_size=0.25', fc="white",
ec="k", lw=2),
transform=ax.transAxes)
Also, annotate command gives you more flexibility in text positioning.
The axes location is supposed to be known during the drawing time. To
get the axes position, you may do something like
ax1._axes_locator(ax1, fig._cachedRenderer)
Of course, this need to be done after the figure is properly drawn
(e.g., after calling draw()) or during the drawing time.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
