This started a long thread involving several suggestions from Martin
Weiss.
The basic class of problems I take to be plotting means and confidence
intervals for various cross-classified groups.
I'd just like to point out that this is, not surprisingly, a problem
often met before. Among various other solutions -stripplot- on SSC
supports -over()- and -by()- options.

I have continuous data for two trial arms (control and experiment).
There are 50 measurements per arm.
Data is collected at 6 time intervals.
I would like to plot a bar chart with the x axis showing the intervals
(0, 1, 3, 6, 9, 12 months). Within each interval I would like to have
one bar for the control and one for the experimental group.
The y axis shows the mean of the measurement of interest.
Additionally, I would like to show the confidence intervals at each
interval per treatment group.
Alternatively, I would like to draw a line plot with the same y and x
axis information, except that the two lines would represent the control
and the experimental groups.
