twoway kdensity ttl exp, clwidth(thick) clpattern(dash)
We can use options such as
clcolor()
,
clwidth()
,and
clpattern()
to alter
the characteristics of the line. Here, we
use the
clwidth()
and
clpattern()
options to make the line thick and
dashed. See
Styles : Linewidth
(337),
Styles : Linepatterns
(336), and
Styles : Colors
(328) for more details.

We conclude by showing how you can
use
twoway
function
to graph an
arbitrary function. We graph the
function
y=normden(x)
to show a
normal curve. We add the
range(-4
4)
to specify that we want the
x
-values
to range from
4 to 4. Otherwise, the
graph would show the
−
x
-values ranging
from 0 to 1.
