Naming graphs drawn with ntuples

ROOT
1

Hi ,
I have hard time to figure out , How I can change title of plots which I have drawn with ntuples. I want to also name X,Y coordinates without using TXTfiles,
For example
c1->cd(1);
ntuple->Draw(“mKPip:mKPi0”,cut);
ntuple->SetTitle(“m^{2}(K^{-}#pi^{+}) and m^{2}(K^{-}#pi^{0})”);
ntuple->SetMarkerStyle(5);
ntuple->SetLineColor(37);

Here I draw ntuple in two dimentions , but I cannot label X,Y coordinates as How I do in drawing TGraphs.
Could you please help me to how to solve this problem,
thanks,

Try this:

{
   TFile F("hsimple.root");
   ntuple->Draw("py:px");
   c1->Update();
   ntuple->GetHistogram()->SetTitle("title");
   ntuple->GetHistogram()->SetXTitle("X title");
   ntuple->GetHistogram()->SetYTitle("Y title");
}
