Subject:      an issue in 9.3 sgplot -loess

Did anyone notice the different results between the following two codes,
event though i bet the two pictures should be same:

proc sgplot data =have;
loess x =x y =y/group =group;
run;

proc sort data =have out =have_s; by group;
run;

proc sgplot data =have_s;
loess x =x y =y /group =group;
run; quit;

my x is in ( 1 2 3) , group in ( a b), and y is continuous.
