基于分组语句，各省份的散点图都能够独立显示了。例如，SAS语句分组绘制的代码如下
options nodate pageno=1 linesize=80 pagesize=35;

  data education;
input State $14. +1 Code $ DropoutRate Expenditures MathScore
      Region $;
label dropout='Dropout Percentage - 1989'
      expend='Expenditure Per Pupil - 1989'
         math='8th Grade Math Exam - 1990';
datalines;
Alabama       AL 22.3 3197 252 SE
Alaska       AK 35.8 7716 . W
