twoway scatter ownhome borninstate [aweight=propval100],
msymbol(oh)
msize(small)
Even if we weight the size of the
markers using
aweight
, we can still
control the general size of the markers.
Here, we make all markers smaller
using the
msize(small)
option. The
markers are smaller than they were
previously but are still sized according
to the value of
propval100
.

We might try to even graph a fourth
variable in the plot by using the
mlabel()
(marker label) option. Here,
we try to use the
mlabel(stateab)
option to label each marker with the
abbreviation of the state. However,
note that when we add the
mlabel()
option, the weights no longer affect the
size of the markers. See the following
example for a solution to this.

twoway (scatter ownhome borninstate [aweight=propval100],
msymbol(oh) msize(large))
(scatter ownhome borninstate,
mlabel(stateab) msymbol(i) mlabpos(center)
)
We can solve the problem from the
previous example by overlaying a
scatterplot that has the symbols
weighted by
propval100
with a
scatterplot that shows just the marker
labels. The second scatterplot uses the
mlabel(stateab) msymbol(i)
mlabpos(center)
options to label the
markers with the state abbreviation.
See
Options : Marker labels
(247) for
more details.
