The UCLA Stata FAQ has a good discussion of this kind of problem:

Subject: st: RE: Further query on twoway bars for 2 rates
I found the solution.
Copy and paste the following sample data:
statefips age senior age_l age_h senior_l senior_h
statefips1 statefips2
1 35.5416 13.7 35.04163 36.04163 13.2 14.2 0.75
1.25
3 28.442 4.3 27.942 28.942 3.8 4.8 2.75 3.25
5 34.4531 13.2 33.95309 34.95309 12.7 13.7 4.75
5.25
7 36.3938 15.8 35.89377 36.89377 15.3 16.3 6.75
7.25
Basically, you generate statefips1 (and 2) by substracting (adding) 0.25 to
statefips. The age_l and age_h are lower and upper bounds artificially
generated for age. The same for senior.
Then, you can use this to create the graph:
twoway (bar age statefips1, barw(.5)) (rcap age_l age_h statefips1) (bar
senior statefips2, barw(.5)) (rcap senior_l senior_h statefips2)
Of course, you need to relabel it a little bit.
Let me know your final results.

Subject: st: Further query on twoway bars for 2 rates
Hi folks,
Thanks to those who replied yesterday. Perhaps my request wasn't clear.
I want to map rates for males and females, with 95% CIs, by a group variable
(e.g. region).
If I use the syntax
#d;
graph twoway (bar rate1 groupvar,(barw(0.5)) (rcap lb1 ub1 groupvar ) (bar
rate2 groupvar, barw(0.5)) (rcap lb2 ub2 groupvar), ; #d cr
I obtain a graph where the bars for males and females and their CI's are
plotted. However, the two bars are upon one another.
Is there a way to somehow shift the rate2 bars and CIs to the right, so that
they have an appearance similar to the command
Graph bar (asis) rate1 rate2, over(groupvar)
With the confidence intervals attached?
Cheers
Dan
