RE: st: dot-dash-plot
Many thanks to Scott and Maarten for this snippet, which I've already
added to my "widgets" folder. I've been wanting this graph technique
for years!

Cool,
It might be improved a bit by adding a jitter to mpg:
sysuse auto,clear
gen wherex = 11
gen wherey = 3000
gen pipe = "|"
gen mpgjit = mpg + .4*invnorm(uniform())
twoway scatter mpg price , msize(small) || ///
scatter wherex price, ms(none) mlab(pipe) mlabcolor(black) ///
mlabpos(0) || ///
scatter mpgjit wherey , ms(none) mlab(pipe) mlabang(vertical)///
mlabcolor(black) mlabpos(0) || , ///
legend(off) yscale(noline) ylabel(none) xscale(noline) ///
xlabel(none) xtitle(Price)
