True! And to make this worthwhile, let the graph editor do its magic...


*************
sysuse auto, clear

set obs `=_N+1'
replace foreign = 0.5 in l

twoway scatter rep78 mpg,/* 
 */  by(foreign, cols(3))

gr play edit
*************

with file edit.grec defined as follows, to be saved to the PERSONAL/grec directory:


*************

.
One possible workaround may be to add fake-observations to your dataset.

Here is an example:

sysuse auto, clear
set obs `=_N+1'
replace foreign = 0.5 in `=_N'
twoway scatter rep78 mpg, by(foreign, cols(3))
