[yt-users] EPS figures in matplotlib (*slightly* off topic)

[Britton Smith]

Hi John,

I've found some success when supplying the "dpi" keyword to savefig.  This
seems to most often work for Cameron's issue by writing to png with
dpi=200.  I've also seen this problem before when writing directly to pdf
and this wasn't able to fix it.  My solution there was just to png and use
convert to convert it to pdf or eps.
