Rebin histogram

Hi @Wile_E_Coyote ,i used your code for the re-binning and it worked, but I had also to cut some data and I need 2 use 2 gaussian fit. Following your reply in this topic Fitting with two gaussian curves , I got a good 2 gaussian fit. Anyway, in the statistical box, I get the mean value of the 2 separated fits, instead I’d like to get also the mean and sigma values of the produced by your code of the total fit.
Should it be possible?
Following @couet reply to this topic Adding text to statistics box I wrote

TPaveStats *statsgdeltatime = (TPaveStats*)htemp->GetListOfFunctions()->FindObject("stats");
   		statsgdeltatime->SetTextColor(kBlue);
   		statsgdeltatime->SetX1NDC(0.80); statsgdeltatime->SetX2NDC(0.98);
   		statsgdeltatime->SetY1NDC(0.77); statsgdeltatime->SetY2NDC(0.92);
   		statsgdeltatime->AddText("Mean	%lf \n #sigma	%lf",mean,sigma);
   		statsgdeltatime->DrawClone();
   		gPad->Update();

but I get error.
