If that were my problem, I wouldn't use -serrbar- at all. You could
use marker labels, but there would no guarantees about readability or
friendliness of display.
This example shows some technique. I used some real data, but faked
standard errors. -labmask- is from SJ and must be installed first. See
my 2008 article for much more. It doesn't touch on your precise kind
of graph, but otherwise I think it is pertinent. It's free as a .pdf
at
http://www.stata-journal.com/sjpdf.html?articlenum=gr0034
sysuse lifeexp, clear
l country in 1/10
gen upper = lexp + 2.4
gen lower = lexp - 2.4
gen axis = _n
labmask axis, values(country)
* next 3 lines are all one command: omit /// interactively
scatter axis lexp in 1/10 || ///
rcap lower upper axis in 1/10, horizontal yla(1/10, noticks valuelabel
ang(h)) ///
ysc(reverse) ytitle("") legend(off) xtitle(`: var label lexp')
Disclaimers:
1. The example graph uses alphabetical ordering by countries, which is
not usually a good idea. It's usually better to choose another order,
e.g. to -sort- by means first.
2. I'm the putative author of -serrbar-, because I rewrote it many
years ago, but it's not nearly versatile enough to do well what you
are likely to want. I feel no conflict of interest in diverting you
away from a command not much use to you really.
