Matplotlib doesn't support \text, and it requires that the first and
last characters of a TeX string be $. I guess it only processes
mathmode. Well, it can't do *everything*. It would be nice to figure
out a workaround...
Gary's example
xlabel(r'\\rm\{Normalized Temperature\} \(kT/\\epsilon\)'
USED to work, in earlier versions of Matplotlib. It no longer does. I have
posted a similar issue a little while ago:
http://sourceforge.net/mailarchive/message.php?msg_id=9681306
Unfortunately, I haven't really had the time to dig into the code to see what
has changed, but when I do, I'll let you know what I find. The solution
xlabel(r'\\rm\{Normalized \\ Temperature\} \(kT/\\epsilon\)'
somehow isn't entirely satisfactory.
As far as I can see, \rm{} in Matplotlib should act just the way \mbox{} does in
LaTeX, when you are already in math mode. And certainly, in LaTeX,
produces the expected output in the expected fonts and with the expected
spacing.
