I assume this is caused by texnum.mp (which is loaded by format.mp
(which is loaded by graph.mp)).

The labels are typeset only once and then cached. This is done using
a btex .. etex construct, lik so:

   init_numbers(btex$-$etex, btex$1$etex, btex${\times}10$etex,
	btex${}^-$etex, btex${}^2$etex)

And that uses the standard TeX math fonts. My guess is that you
can fix your problem with an appropriate verbatimtex ... etex preamble.
