This graph extends the previous
example by adding a second point for
Hawaii and providing a position for the
marker label for Hawaii, placing it at
the 8 o'clock position. In addition, the
legend(off)
option suppresses the
legend. Finally, this graph uses the
vg samec
scheme, so the markers
created via
scatteri
look identical to
the other markers.

This section concludes by looking at some additional graph commands that make graphs
similar to
twoway scatter
, namely,
twoway spike
,
twoway dropline
,and
twoway dot
.
Most of the options we have illustrated before apply to these graphs as well, so they will
not be repeated here. We will switch to using the
vg blue
scheme for the rest of the graphs
in this section.
twoway scatter r yhat
Imagine that we ran a regression
predicting
propval100
from
urban
and
generated the residual, calling it
r
,and
the predicted value, calling it
yhat
.
Consider this graph using the
scatter
command to display the residual by the
predicted value.
