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
