Nick Cox suggests that multiple lines can be distinguished by line style
and a key. Here's another alternative, offered to underline one reason
for advocating Stata as a graphics tool: its facility for creating and
revising graphics in a design-review-edit cycle.
Given several series, var names ser1, ser2, ser3 etc ...
gr ser1 ser2 year, s(..) c(ll) /* simple line graph */
gen id1=1
gen id2=2 /* etc */
gr ser1 ser2 year, s([id1][id2]) c(ll) /* labels every point */
/* may be too cluttered if there are many points */
gen last1=1 if(_n==_N)
gen last2=2 if(_n==_N) /* etc */
gr ser1 ser1 ser2 ser2 year, s(.[last1].[last2]) c(l.l.) pen(2233)
/* puts a label at the end of each line, in same colour as line */
/* but beware if _Nth value of series is missing! */
Of course, "last1" etc may be string variables to label each line with
a label sensu strictu.

The management here were SO impressed with W Edward Deming's "Out of
the crisis" that they are working flat out to create THE BEST crisis,
so we can start implementing the 13 points.
