Hi, I have tried, without success to create a 3D ntuple draw that goes into a previously defined TView and I always get empty plots. What I did was this: myCanvas = new Canvas("myCanvas","Quill plots",200,0,550,650); myCanvas->Divide(1,2); myCanvas->cd(2); TView *view = new TView(1); float range = numberOfCircles*d; view->SetRange( -1.0, -1.0, 0, 1000, 1000, 10 ); ntuple->draw("x:y:z","","same") When I leave the "same" option in the draw() the ntuple is correctly drawn but not in the view I wanted but in the automatically calculated view that spans the whole of the data. What now? cheers Armin ************************************************* * Dr. Armin Reichold | private: * * Research Officer | 17 Frys Hill * * University of Oxford | Oxford * * Particle & Nuclear Phys.
