Sure. If you use -egen-'s -median()- and -mean()- functions to get the variables you want, then it's any graph you want. As the median and mean values are repeated, don't plot them repeatedly. Here are some dopey examples. . webuse grunfeld . egen median = median(invest), by(year) . egen mean = mean(invest), by(year) . egen tag = tag(year) . line mean median year if tag For finer subdivisions, just use more variables as arguments to -by()-.

I think I can do this by collapsing the data but is it possible to do this while retaining the data set in its 'original' state. I have searched the archives and the reference manuals but have not come up with anything that seems to be what I want. > In many ways what I would like is a box plot with JUST the median (or mean) being plotted: no box, no outliers.
