This is pretty neat, Scott, but what if you want to change this to show
the graph as, say, thin(ish) horizontal bars? I changed -bar- to -hbar-
everywhere in the code, but it threw up error messages, so obviously I was
doing something wrong! That said, I was able to add extra bars for extra
variables without too much difficulty.

That leads to the second question. If you're like me and you're running a
model with 50 variables, presumably there's no quick-and-dirty workaround.

Third, what if Alex wanted to use beta-weights as opposed to b-scores?
Unfortunately, -ereturn list- doesn't leave these behind even if you enter

. reg price disp length, beta

but, again, maybe there's a workaround here, too. Thanks also to Alex for
putting the question.
