Re: st: Adding error bars to bar chart

["Roger B. Newson" <r.newson@imperial.ac.uk>]

I would always use the SSC package -eclplot- in these circumstances. It 
does 56 types of confidence interval plot, corresponding to all the 
combinations of the 7 possible values for the -eplottype()- option 
(specifying how to display estimates)combined with 8 possible values for 
the -rplottype()- option (specifying how to display confidence limits). 
The options

eplottype(bar) rplottype(rcap)

give the familiar "detonator plot" (ie bars with error bars) that Chris 
seems to want.

I hope this helps.

Best wishes

Roger
