The briefest suggestion is "Don't do that" for reasons developed
(e.g.) in the thread starting
http://www.stata.com/statalist/archive/2013-05/msg00293.html
and its references.
A less cryptic comment would be that this almost always (1)
over-reduces the data (2) places most emphasis where it is least
appropriate (3) is more difficult to interpret than easy alternatives.
There is no difficulty in principle, except that if you think the
place to start is -graph bar- that is quite wrong. You would need to
start with -twoway bar- and then add other -twoway- elements. By the
same token, you would need to calculate everything you need as
variables before you enter -twoway-.
