Yes,

All text commands in xplt allow some simple formatting.

Greek characters:

prepend with a ! so xplt.xlabel('!a!b') should produce alpha beta (you 
have to know   the letter equivalent of the Greek symbol you want)
xplt.xlabel('!a!b!c!d!e!f!g!h!i!j!k!l!m!n!o!p!q!r!s!t!u!v!w!x!y!z')
should give you an idea of these.

Subscripts:  embed in '_'

xplt.xlabel('H_2_O')

Superscripts:  embed in '^'

xplt.xlabel('x^2^+y^2')


Look at

xplt.xlabel('!l^2^ !n_2_^2^+3')
