I did not see an option you could do that either.
The workaround way I could image is using PROC SGPLOT to make a picture for LEGEND and insert this picture into PROC SGRENDER by rotating it 90 degree.
But that would cost you a lot of time and you need to make legend be consistent with original graph.
Here is an example:
%let path=%sysfunc(pathname(work)); *the path stored the picture ;
*Make a picture for Legend;
data x;
input label $ x y s_male_x s_male_y male $ male_x male_y s_female_x s_female_y female $ female_x female_y;
cards;
SEX 0 0 1 0 Male 1.5 0 2.5 0 Female 3.2 0
