Side-By-Side vs. Overlayed Plots

At the risk of delving too deeply into Stata's graphics coding "weeds," two different ways to present the same graphs help illustrate graphing possibilities.

By convention, a "side-by-side" presentation of two distinct, though related, plots (with confidence intervals) in Stata looks like the following:

If the plots are snug enough in how they relate, however, additional coding can produce a single "overlayed" graph:

For those intrigued, the coding underneath these two possibilities is included here.
