Title for x−axis
twoway
dropline
r yhat,
msymbol(Oh)
A
twoway dropline
plot is much like a
spike
plot but permits a symbol, as
well. It supports the
horizontal
,
base()
,
blcolor()
,and
blwidth()
options just like
twoway spike
, so these
are not illustrated. But you can use
marker symbol options to control the
symbol. Here, we add the
msymbol(Oh)
option to obtain hollow circles as the
symbols; see
Options : Markers
(235) for
more details.

twoway dropline r yhat, msymbol(O)
msize(vlarge)
mfcolor(gold) mlcolor(olive) mlwidth(thick)
Here, we make the symbols very large
circles and use
mfcolor()
to make the
marker fill color gold,
mlcolor()
to
make the marker line color olive, and
mlwidth()
to make the marker line
width thick. For more information, see
Options : Markers
(235).
