Variants on this problem arise quite
frequently on this list.
If you
. sort id x
. twoway connected y x, c(L)
you should get what you want if the
data are unproblematic. Alternatively
. ssc inst linkplot
. linkplot y x, link(id)
is in some respects a more general
tool which does not, or at least
should not, hinge on (1) having
exactly the best sort order (2)
a full set of -id- * -x- combinations.
