Lixiaoyao,

  Maybe something like this is what you are looking for?

data fisherf;
do ndf=5 to 60 by 5;
do ddf=5 to 60 by 5;
do x=0 to 5 by .02;
 y=pdf('F',x,ndf,ddf);
 output;
end;
end;
end;
run;


symbol v=none cv=blue i=j;
proc gplot data=fisherf uniform;
plot y*x/vm=0 hm=0 ;
by ndf ddf;
run;
quit;

Regards,

RVV
