Hi,

when drawing by Draw(), the axis title of TH3 histogram seems. But not seem when drawing by Draw(“AXIS”)

 		     GAINHVCorr->Fill(GAINfor650,GAINfor700,HV[hv]);
                     GAINHVCorr->SetFillColor(2);
                     GAINHVCorr->SetMarkerColor(kRed);
                     GAINHVCorr->SetMarkerStyle(8);
                     GAINHVCorr->GetXaxis()->SetTitle("GAINfor650V");
                     GAINHVCorr->GetYaxis()->SetTitle("GAINfor700V");
                     GAINHVCorr->GetZaxis()->SetTitle("HVs");
                     
                     GAINHVCorr->Draw("AXIS");

Cheers,
Ersel

Why ? Draw(“AXIS”) draws just Axises without titles
