The "note: label truncated to 80 characters" message you get when you
run the above -stcurve- command is referring to the label used internally by
Stata when producing the graph. It does not affect the -at- option used in
the command. Neville has overwritten the default labels used in the legend
of the graph with his own labels (which is the best option). If the -legend-
option was taken off the above command, the 80 character labels (those that
were truncated) would appear and would be hard to read. Thus, the note is
just a good reminder to check the truncated labels when the graph is
produced and to possibly create new ones manually.
