可以用 Proc Gbarline, 但这个过程还不完善，不能画图例legend. SAS9.2中将可以实现。

太好了，非常感谢

Creating Bar Charts and Scatter Plots on the Same Page, you can Use PROC GPLOT or PROC GBARLINE in SAS

程序
proc gplot data=urine;
plot urine1*asdt/ noframe nolegend haxis=axis1 vaxis=axis2;
plot2 labval*asdt / noframe nolegend haxis=axis1 vaxis=axis3;
run;
quit;

proc gbarline data=urine__;
   format asdt datetime16.;
bar asdt/ sumvar=urine__ width=1.5 discrete noframe space=1 axis=axis2  
maxis=axis1;
   plot /sumvar=labval axis=axis3;
run;
quit;
