.

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

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.

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?

much thanks,
Chris
