graph bar wage, over(occ7) asyvars
This is another example of where a
legend can arise in a Stata bar graph by
specifying the
asyvars

treats an
over()
variable as though the
levels were different
-variables.

Unless otherwise mentioned, the legend options described below work the same regard-
less of whether the legend was derived from multiple
-variables or from an
over()
variable
that was combined with the
asyvars
option. These next examples use the

scheme.
