Regarding the second question of my original message:
I'd like to be able to have multiple levels by which the plots are separated/grouped along the x-axis (like the "over" command in "graph box" allows). For example, using eclplots, I'd like to be able to include two "parmid_varname" variables....or using ciplots, I'd like to include two variables in the "by" option.
Now, I've also plotted this data by overlaying rcap plots with scatter plots of the means. Using this plotting method, is there a way to horizontally offset the rcap plots within a single x-axis value so that the rcaps do not overlap? This might be an acceptable presentation for me as well, although it would be better if I could do this through ciplot, eclplot, or serrbar.

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

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...

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.
