Hi rooters,
I have a canvas in which I draw 2 graphs using TMultiGraph. I fit these
two graphs with "pol0".
I'd like to print in the Canvas the two boxes with fit parameters but I
get only one (the parameters of the second fit).
How to print the two boxes with fit results ?
root 4.02/00, Mac OS X.3.
Thanks !
Cheers,
Julien
TCanvas *c2 = new TCanvas("title", "title", 9,44,699,499); c2->SetFillColor(kWhite); c2->SetFrameFillColor(kWhite); TH1F *hfname2 = c2->DrawFrame(0.2, 0, 1.8, 200); hfname2->SetTitle("Energy"); hfname2->SetXTitle("Kl");
TGraphErrors *gr2 = new TGraphErrors(9, KL, EN1, 0, ERREN1); gr2->SetMarkerStyle(5); gr2->SetMarkerColor(kBlue); TGraphErrors *gr3 = new TGraphErrors(9, KL, EN2, 0, ERREN2); gr3->SetMarkerStyle(5); gr3->SetMarkerColor(kRed); TMultiGraph *mg = new TMultiGraph(); mg->Add(gr2); mg->Add(gr3); mg->Draw("P"); gr2->Fit("pol0"); TF1 *fline2 = gr2->GetFunction("pol0"); fline2->SetLineColor(kBlue); gr3->Fit("pol0"); TF1 *fline3 = gr3->GetFunction("pol0"); fline3->SetLineColor(kRed);Received on Wed Mar 02 2005 - 13:18:07 MET
