Hi Guang,

Coincidentally, I was just wrestling with the same thing myself
yesterday.  Here is the command I used:

kdensity var if (year==1999), plot(kdensity var if
(year==1989)||kdensity var if (year==1979)) legend(ring(0) pos(2)
label(1 "1999") label(2 "1989") label(3 "1979") )

Hope this helps!

Chris
