graph dot tenure, over(grade) over(collgrad)
Consider this dot plot, which breaks
tenure
down by two variables: the last
grade that one completed and whether
one is a college graduate. By default,
Stata shows all possible combinations
for these two variables. In most cases,
all combinations are possible, but not
in this case, and including them has
caused the labels for grade to overlap.

that exist in the data, you can use the

Options for groups, over options
This section considers some of the options that can be used with the
over()
and
yvaroptions()
options for customizing the display of the markers. We will focus on con-
trolling the spacing between the markers and the order in which the markers are displayed.
Other options that control the display of the
x
-axis (such as the labels) are covered in
Dot : Cat axis
(202). For more information on the
over()
options covered in this section, see
the
over subopts
table in [
G
]
graph dot
. We first consider options that control the spacing
among the markers and then options that change the order in which the markers are sorted.
These examples begin with the
vg blue
scheme.
