Hi Jonathan,

You can do:

 tree.Draw("x:y:z");
 htemp->SetTitle("a global title;x title; y title; z title")

or
 htemp->GetXaxis()->SetTitle("x title");
 htemp->GetYaxis(.. etc

or
 TH3F *h = new TH3F("hname","a global title;x title; y title; z 
title",nbinsx,
   xmin,xmax, nbinsy, ymin,ymax, nbinsz, zmin,zmax);
 tree.Draw("x:y:z>>hname");
