Yes, and the principle is pretty much the same in the example I sent
earlier:
*-------------- begin example --------------
sysuse nlsw88, clear
xtile quintile = wage, nquantiles(5)
twoway kdensity tenure if quintile==1 || /*
*/ kdensity tenure if quintile==2 || /*
*/ kdensity tenure if quintile==3 || /*
*/ kdensity tenure if quintile==4 || /*
*/ kdensity tenure if quintile==5
*-------------- end example ----------------
