st: about graph bar

["G. Dai" <dgecon@gmail.com>]

Dear all, here is my question. I have data on individual weight, gender, and
a dummy indicating
if the individual does exercises often. I want to compare if often exercise
is correlated with weight.
thus, I first
 .graph bar weight,over(exercise)
and to compare the gender difference I also
.graph bar weight,over (exercise) over(gender)
As you can see I get two graphs one separating  gender effect one not.
However, to save space,
I'd like to combine these tow graphs in one,that is one  graph  with three
type bars:male female and mixed.
thanks,
Guang
