graph hbar wage hours, over(occ7, sort(2)) over(married, descending )
Each over() option can have its own
separate sorting options. In this
example, we add the descending
option to the second over() option,
and the levels of married are now
shown with those who are married
appearing first.

graph hbar (sum) wage, over(collgrad) over(occ7) asyvars stack
Say that we were to graph the sum of
wage broken down by collgrad and
occ7 . We further treat the levels of
collgrad as

-variables and form a
stacked bar chart. We might want to
sort these bars based on the sum of
wages for each occupation. See the next
example for how we can do that.

graph hbar (sum) wage,
over(collgrad) over(occ7, sort((sum) wage) ) asyvars stack
Here, we add sort((sum) wage) to the
over() option for occ7 , and then the
bars are sorted on the sum of wages at
each level of occ7 , sorting the bars on
their total height.
