SAS sgplot：按组分组的不同符号和颜色

Question

以下代码生成下图。 如您所见，group语句会为数据点生成不同的颜色。

问题：我怎样才能为这两组提供不同的符号？

   proc sgplot data=test;
        scatter x=time y=Y / group=group;
    run;

group   time    Y

使用http://www.ats.ucla.edu/stat/sas/faq/gr2grps_new.htm：

symbol1 v=star c=red h=1;
symbol2 v=triangle c=blue h=1;

proc gplot data=temp;
    plot y*time=group;
run;
quit;
