You can ask -kedensity- to save the variables, and then use those.
See the example below:
*---------- begin example ----------------
sysuse auto, clear
kdensity price, gen(x y) at(price) nograph
twoway line y x, sort || /*
*/ scatter y x, msymbol(+) name(plus, replace) legend(off)
* I actually like a rug plot underneath the smooth better:
gen y1 = 0
gen y2 = .00001
twoway line y x, sort || /*
*/ pcspike y1 price y2 price , legend(off)
*------------- end example ----------------
Hope this helps,
Maarten
