Another strategy for controlling the
marker symbols is choosing or creating
a scheme. The
vg samem
scheme makes
all markers the same size, shape, color,
etc., allowing you to customize them all
from a common base. Here, we use the
vg samem
scheme, making all markers
solid, dark gray circles, but use the
msymbol(. Sh)
option to make the
second symbol hollow squares.

Say that you wanted the markers to be
displayed as outlines filled with white.
Rather than specifying the
mfcolor()
option, you could use the
vg outm
scheme, as shown here. Even if you
overlaid multiple commands, using this
scheme would display the markers, by
default, as white-filled outlines.

Creating and controlling marker labels
This section looks at the details of using marker labels. Marker labels can be used to
identify the markers with
graph twoway
but also can be used with other types of graphs,
such as
graph matrix
and
graph box
, affecting the outside values. You can even use
marker labels in lieu of markers. For more information, see [

]
marker label options
.
For this section, we will use the
vg s2c
scheme and the
allstates3
file, which keeps the
states that are in the South, i.e., if
region
is equal to 3.
