Hi Rooters,
I have problem with fitting my data by power law function at this way:


     Elow=15.0;
     Ehigh=500.0;
     f1 = new TF1( "f1", "pow(10,[0]*x+[1])", log10(Elow), log10(Ehigh)
);
     f1->SetLineColor(4);
     f1->SetLineWidth(1);
     hist->Fit("f1","R");


I have received result like on the figure which I attached to my e-mail.

The histogram 'hist' was rescaled earlier.
What is wrong in my code?

Best regards,
   Janek.
