Hi! I am using matplotlib 0.99.0 under windows xp. I tried the following:
ax.text(.96,.80,r'$P \perp
Q$',fontsize=18,horizontalalignment='right',verticalalignment='top',transform=ax.transAxes,color='black')
and get the following error:
(However, in figure labels, symbols using mathtext, such as theta seem to
work fine...)
Thanks,
William
