thanks for the example Svend!
I was thinking of doing something like your code,
"replace race=race-0.03 if smoke==0
replace race=race+0.03 if smoke==1"
for offsetting the plots, and this code will take the error out of my "trial and error" approach to getting the appearance I want. I'll make use of your xlabel code as well!
thanks again Nick, David, and Svend
Chris

I would like to know how to take the means and standard errors
calculated from the "ci" command, and plot the means with brackets
placed at plus/minus the standard error.
1) So, I first need to know how to get these estimates into a
dataset for use.
2) I found the "serrbar" command, which will do a basic plotting,
but what I'd really like is to have a way to group these estimates,
much like the way you can with "graph box" and the "over" option.
Is this possible?
and later:
... is there a way to horizontally offset the rcap plots within a
single x-axis value so that the rcaps do not overlap?
===================================================================
I find -statsby- most convenient to extract a condensed dataset
with the estimatess of interest. The example also demonstrates
a way to horisontally offset the rcaps:
webuse lbw.dta, clear
statsby mean=r(mean) se=r(se), by(race smoke) clear : ci bwt
generate ub = mean + se
generate lb = mean - se
replace race=race-0.03 if smoke==0
replace race=race+0.03 if smoke==1
twoway (rcap lb ub race)(scatter mean race) , ///
xlabel(1 "white" 2 "black" 3 "other") ///
ytitle("Birthweight (grams)") ///
legend(off)
Hope this helps
