This topic has been discussed several times on Statalist 
over the last few months. Possibly no topic has engendered 
such passionate exchanges on Statalist in 2003. 

In the archives, you can see, for example, a thread started
by Buzz Burhans in early June and another thread started by 
Fred Wolfe in late June. The contributions ranged all the way 
from why it is one of the biggest gaps in official Stata, to
why this is a very bad idea, to some code letting you do it, 
or something like it. 

In particular, I posted some code on Statalist on 30 June, 
building on a suggestion by Stephen McKay. I didn't get 
any comments, public or private, on whether it was 
quite what people wanted. 

It shouldn't be too difficult to write a version of 
-ciplot- to do confidence intervals shown as these bar on bar 
plots, but I await expressions of interest in using that 
program before I actually write it.
