It should also be noted that attributes like "weight" and "stretch" are 
only hints for the purpose of finding a font. That is, if you request a 
bold version of a font, and it does not exist, the closest matching font 
will be used instead. matplotlib (more specifically freetype) does not 
do "font synthesis" to generate a pseudo-bold font or pseudo-compressed 
font if one can not be found. So for example, the "condensedFont" set of 
properties you defined will not return a condensed font unless such a 
font exists on your system.

Do you have fonts whose family name is "sans serif"?
Maybe you meant "sans-serif"?

"sans-serif" searches for fonts whose family name is in
rcParams["font.sans-serif"], but "sans serif" only search for "sans
serif".

I don't think it has anything to do with annotation.
Check if findfont gives you a correct font.
Please report back with matplotlib version etc., if findfont finds a
correct font but annotation still shows with a wrong font.

Regards,

import matplotlib.font_manager
fm = matplotlib.font_manager.fontManager
print matplotlib.font_manager.findfont(normalFont)
