你可以试试用ods graph模块画图，非常方便，自动生成code

proc sgplot data=sashelp.cars noborder;
  styleattrs datacolors=(red blue);
  vbar type / response=mpg_highway stat=mean
       dataskin=none barwidth=0.4  
       baselineattrs=(thickness=0)
       discreteoffset=-0.2;
  vbar type / response=mpg_city stat=mean
       dataskin=none barwidth=0.4  
       baselineattrs=(thickness=0)
       discreteoffset= 0.2;
  xaxis display=(nolabel noline noticks);
  yaxis display=(noline) grid;
run;

proc sgplot data=sashelp.class
   dattrmap=myattrmap;
vbar age / response=height group=sex
   groupdisplay=cluster attrid=myid;
run;

谢谢指导
