eval関数を使ってGTL内で関数使用

data Q1;
 do Z= 1 to 10;
  X=rand('uniform');Y=rand('uniform');
  output;
 end;
run;

proc template;
 define statgraph G1;
 begingraph;
 layout overlay;
  scatterplot x=X y=Y
    /name='n1'
     markerattrs=(size=11 weight=bold symbol=circlefilled)
     group=eval(ifc(Z<=5,'low','high'));
   discretelegend 'n1'/title='Z'
                        location=inside halign=right valign=bottom;
  endlayout;
  endgraph;
  end;
 run;

 proc sgrender data=Q1 template=G1;
 run;
