You could probably figure out a way to create an IDLgrAxis
object using the same range, divisions, etc. as your direct
graphics axis. Then inquire of the object what its tick values
are. Then destroy the object and create your direct graphics
plot. I think the algorithms used for direct and object graphics
are very similar, if not identical. You could even use the
object tick values as input to your direct graphics plot if
you wanted to.
Cheers,
