Hello,

   In the root_v4.01.02.Linux.RH7.3.gcc296 environment,I failed to run the macro like this:    

      {
        Float_t a[4]={450,1050,1431,1983};
       Float_t  b[4][4]= 

{1576,3420,4854,6635,117,262,402,528,21,53,71,93,4,18,24,28};  TCanvas *c1=new TCanvas("c1","",1);
 c1->Divide(2,2);
 for(i=1;i<5;i++)
  {
  c1->cd(i);
  gr[i-1]=new TGraph(4,a,b[i-1]);
  gr[i-1]->Draw("AL*");

  }

      }
 Would you help me to succeed in running it?  Thank you in advance.   

with best wishes,
