Hi, I've the following piece of code which draws an ntuple under a
condition. However, if one looks at the plot, one would notice that it's
the z variable, not the x variable, that's constrained according to the
cut. Is this a bug? If so, would you fix it?
Thank you so much
john

{
gROOT->Reset();
  
  TCanvas *canvas = new TCanvas("canvas","foo",200,10,700,780);
  TNtuple *ntuple = new TNtuple("ntuple", "data from ascii file",
"x:y:z:v");  
  ntuple->ReadFile ("foo");
  
  ntuple->Draw ("x:y:z:v", "x < .1 && x > -.1");

TH1F *htemp = (TH1F*)gPad->GetPrimitive("htemp");
htemp->SetXTitle("x");
htemp->SetYTitle("y");
htemp->SetZTitle("z");
}
