graph hbox wage,
nooutsides note("")
over(collgrad) over(urban2) over(married)
Consider this box graph, which breaks
wages down by three categorical
variables. If we wanted to further break
this down by another categorical
variable, we could not use another
over()
option since we can have a
maximum of three
over()
options with
a single
Rural
single
Metro
Rural
married
-variable. We use the
nooutsides
option to suppress the
display of outside values for this graph
and the rest of the graphs in this
section.

If we want to further break

down by
union
, we can use the
by(union)
option to do this. We also
add the
note("")
option to suppress
the note saying that the outside values
have been omitted.
