Also note -ciplot- from SSC.  

David gave a very interesting reference new to me. Thanks for that. In
W.S. Cleveland. 1994. The elements of graphing data. Summit, NJ: Hobart
is good on graphing error bars.

also see ecloplot for an estimate and confidence limits plot for an  

findit eclplot finds it for you inside stata...

also see a recent paper on different error bars that might be used...

The Journal of Cell Biology, Vol. 177, No. 1, April 9, 2007 7-11

Email me if you don't have access to the paper.

If you really want the means and standard errors you can collapse the  
data set to to means, sd, and counts, derive the sems, and then plot  
means and sems with a scatter and rcap plot combined in a twoway graph.
