I would like to include the following LaTex command in the legend of a
plot in IDL...
$ \widetilde{ B^{ijk}_{0} } $
however TeXtoIDL("...") and IDL 8's internal '$...$' system does not
support the \widetilde{} command. Is there a way of including this
symbol into eg the TeXtoIDL lookup table, or of including the whole
character in another way (maybe I crop it as an image and manually
place it into the legend using TV - last resort)?
I assume this sort of issue has come up before, but have not found an
obvious fix in this case.
I have tried code such as...
B_tilde == '!3 !s $B^{ijk}_{0}$ !r !u ~ !n'
which gives a B with a tilde above, however the tilde is not streched
to cover the superscript as well, and is not positioned high enough to
even sit well above the B let alone the whole symbol. I should add
that this is postscript output to a .esp plot
Any ideas would be great
Thanks

To get an idea of the result,
this is a plot I produced when I was testing
psfrag to decide if it was worth it.
