In the example at the bottom of
http://matplotlib.sourceforge.net/users/annotations.html
you see an example where the horizontalalignment is specified. Can you
just do something like the following?
plt.annotate(annotateTitle, xy=(1,1), xytext=(20,50), xycoords='data',
textcoords='offset points', horizontalalignment='center')
plt.annotate(annotateText, xy=(1,1), xytext=(20,20), xycoords='data',
textcoords='offset points', size='small', color='black',
horizontalalignment='center')
You also see examples of the alignment parameters at
http://matplotlib.sourceforge.net/examples/pylab_examples/annotation_demo.html#pylab-examples-annotation-demo
