Nice alternatives are:
*---------- begin example -------------
sysuse auto, clear
/*if you have many cases*/
twoway kdensity price if foreign == 1 || /*
*/ kdensity price if foreign == 0, /*
*/ legend(label(1 "foreign") label(2 "domestic"))
/*if you have few cases*/
dotplot price, over(foreign)
*----------- end example --------------
(For more on how to use examples I sent to the Statalist, see:

Hope this helps,
Maarten
