[yt-users] EPS Multiplot

Hi John,

Yeah that makes a lot of sense to me. That way the API becomes a lot more
robust and should work better under timeseries multiplots. I'm away from my
computer at the moment but I think the PlotWindow references the pf in some
way in the init?

I also had a look at hg log before I had to run and it was there alright.
No big deal - it was probably something else.

I also came across a couple of other small issues on the multi plot today
when I was testing it. I'll send them on tomorrow and the work arounds when
I get back to the office tomorrow.

Cheers,
John
