Dear Rooters,
    I have a histogram which should be fitted with different formulars
in different ranges. I use the "R+" option to implement this function.
But with gStyle->SetOptFit(1) I got only the parameters of the first
formular in the statistic box. my code is following:



  myfunc1 = new TF1("myfunc1", "[0]+[1]*(950.-x)**2", 950, 1014);
  myfunc1->SetLineColor(6);
  myfunc1->SetLineWidth(1);

  myhisto->Fit("myfunc1", "R0");
         gStyle->SetOptFit(1);
  myfunc1->GetParameters(&par[0]);
  myfunc1->SetParameters(par);
  myfunc2 = new TF1("myfunc2", "gaus",1014 ,1030);
  myfunc2->SetLineColor(6);
  myfunc2->SetLineWidth(1);

   myhisto->Fit("myfunc2", "R0+");
        gStyle->SetOptFit(1);


How can I get the rest parameters' values? Thanks for any help.
    Best Regards                Wen Mei
