I'm trying to create a 3D Histogram from a TNtuple as follows: TFile f("hsimple.root"); TNtuple *n = (TNtuple *)f.Get("ntuple"); n->Draw("pz:py:px>>hh","","goff"); hh->Draw(); The histogram hh is created, but the axes are not set, and hence, hh be drawn. A simple fix is to replace the third command with: n->Draw("pz:py:px>>hh"); but this draws a 3D view which I do not need. In the 2D below, the "goff" option works just fine. Is this the desired behavior? If so, is there a simple way to keep the 3D view from appearing? TFile f("hsimple.root"); TNtuple *n = (TNtuple *)f.Get("ntuple"); n->Draw("py:px>>hh","","goff"); hh->Draw(); Thanks for your help, Glen
