twoway line high low close tradeday, sort
clstyle(p1 p1 p2)
When we graph multiple
-variables, we
can use
clstyle()
(connect line style)
to control many characteristics of the
lines at once. Here, we plot the high
and low prices with the same style,
p1
,
and the closing price printed with a
second style,
p2
.

twoway line high low close tradeday, sort clstyle(p1 p1 p2)
clwidth(thick thick .)
Here, we combine
clstyle()
and
clwidth()
to make the lines for the
high and low prices the same style and
make them both thick. The third line is
drawn with the
p2
style, and the
thickness is left at its default value.

twoway (scatter propval100 urban) (lfit propval100 urban)
We return to the
allstates
data file.
We can overlay multiple twoway
graphs. Here, we show a common kind
of overlay: scatterplot overlaid with a
linear fit between the two variables.
Note that both the
scatter
command
and the
lfit
command are surrounded
by parentheses.
