```-graph twoway- often provides proper solutions for difficult
graph-problems. Here is a starter:

---------------------------------------------------------
clear
set mem 100m
sysuse auto
bys foreign: g counter = _n
contract counter

graph twoway ///
|| bar _freq counter, ///
|| scatter _freq counter if mod(counter,2)==0 ///
, ms(i) mlab(_freq) mlabpos(12) ///
|| , yscale(range(0 2.5)) ylab(0(1)2) legend(off)
