In-Depth Information
While the previous examples (and other examples in this topic) have used the parenthet-
ical notation for overlaid graphs, Stata also permits double vertical bars (
||
) for separating
graphs. To illustrate this, some of the graphs from above will be repeated using this nota-
tion. These examples will be shown using the
vg s2m
scheme.
twoway scatter propval100 urban
||
lfit propval100 urban
We switch back to the
allstates
data
file. Here, the
||
notation is used to
separate the
scatter
command from
the
lfit
command.
