While playing around with the TeX support in matplotlib (rc('text',
usetex=True)) and the PDF backend I noticed an interesting phenomena whereby
the summation symbol in my plot was rendered at a larger size than regular TeX
Taking the following example as my basis
created a PDF and compared it, in Evince to a PDF with an equivalent math
section created by LaTeX.
Overlaying the two PDFs results in the following:

from matplotlib while the top LaTeX. For some reason the summation symbol is
larger in matplotlib than in LaTeX.
I have seemingly confirmed this with latex + dvipdfm and pdflatex.
Does anyone know what might be causing this? The document font sizes are the
same and I tried to match the LaTeX file as closely as possible to the one used
internally by matplotlib.
Polemically yours, Freddie.
