twoway (scatter rent700 ownhome )
(scatter propval100 ownhome,
yaxis(2)
)
Consider this overlaid twoway graph.
The two
-variables are both scaled in
percentages, but they have different
ranges. We use the
yaxis(2)
option on
the second
scatter
command to place
that axis on the second
y
-axis, which is
then placed on the right axis.

ytitle("Percent rents over $700",
axis(1)
)
ytitle("Percent homes over $100,000",
axis(2)
)
Now that we have two
-axes, the
ytitle()
option would change the
y
y
-axis, unless we
specify otherwise. In this example, we
supply a
ytitle()
option with the
axis(1)
option to indicate that the
title belongs to the first
-title for the first
y
-axis, and a
second
ytitle()
option using the
axis(2)
option to indicate that the
second title belongs to the second

Setting and controlling axis labels
This section describes more details about axis labels, including major and minor (nu-
meric) labels, major and minor tick marks, and grid lines. This section also shows how
to control the appearance of these objects (e.g., size, color, thickness, or angle). For more
