我的本意是在图中相应的点有选择地标出第三个坐标来,但我发现用下面的程序得到的结果更好,虽然我没有解决掉最初的问题:
goptions reset=all;
proc gplot data = work.starthalfduration2;
plot ampres*angres;
where fre>=80&&fre<=500;
run;
goptions reset=all;
proc gplot data=work.starthalfduration2;
symbol pointlabel=("#fre");
plot ampres*angres;
where fre in (80,90,100,110,120,130,140,150,160,170,180,190,200,210,220,230,240,250,260,270,280,290,300,310,320,330,340,350,360,370,380,390,400,410,420,430,440,450,460,470,480,490,500);
run;
quit;
输出是两个图.一个是总趋势,一个是第三个坐标的变化趋势.我用的是SAS9.1.3. |
