twoway scatter educ popden,
xscale(log)
We briefly return to the
allstates
file
to illustrate the
xscale(log)
option.
The
xscale(log)
option indicates that
the
-axis should be displayed on a log
scale. Note that the labels for the
x
x
-axis overlap each other.

xlabel(1 10 100 1000 10000)
Here, we use the
xlabel()
option to
change the labels for the
-axis using
the values 1, 10, 100, 1000, and 10,000,
and you can see how these powers of 10
are more equally spaced, reflecting the
log scale of the
x
-axis.

We now return to the
sp2001
data.
You can use the
xscale()
and
yscale()
options to control the axis
lines. In this example, we make the
x
-axis line thick by specifying
xscale(lwidth(thick))
.
