Maartens answer refers to the -addplot- option, which is unavailable for 
-graph hbar-, as far as I know. You might also give -graph twoway bar- a try. 
Consider the command

. sysuse auto
. graph hbar (mean) trunk, over(rep78, sort((mean) trunk)) yline(10)

This can be translated to -graph twoway bar- as follows:

. collapse (mean) trunk if rep78<., by(rep78)
. egen axis = axis(trunk), reverse label(rep78)  // <- Download -egenmore-
. graph twoway 
    bar trunk axis, horizontal barwidth(.5) 
    xscale(range(0 16)) xlabel(0(5)15)

You can than overlay any -twoway- plot you like. In your case overlaying a 
simple line graph is the most natural choice:

. gen line = 10
. graph twoway 
  || bar trunk axis, horizontal barwidth(.5) 
  || line axis line, sort 
  || , xscale(range(0 16)) xlabel(0(5)15) 

Note that the order of the overlays define what is graphed on top of each 
other.

Hope this helps
Uli
