Hi Florian, An example Rene Brun void g3d() { Int_t i; const Int_t N = 5000; Float_t x,y,z; TNtuple T("T","3-d tests","x:y:z"); TRandom r; for (i=0;i<N;i++) { x = r.Gaus(0,1); y = r.Gaus(0,1); z = TMath::Sqrt(x*x+y*y); T.Fill(x,y,z); } TCanvas *c1 = new TCanvas("c1","test",10,10,1100,900); c1->Divide(2,2); c1->cd(1); T.Draw("z:y:x"); c1->cd(2); TH3F *h3 = new TH3F("h3","test 3-d",15,-3,3,15,-3,3,25,0,5); h3->SetMarkerColor(kRed); h3->SetFillColor(kBlue); T.Draw("z:y:x>>h3","","scat"); c1->cd(3); T.Draw("z:y:x>>h3","","box"); //best with with x3d c1->cd(4); T.Draw("z:y:x>>h3","","iso"); //you need the CVS version for this one } On Mon, 10 Jun 2002, Florian Schopper wrote: > > Dear Rooters, > > I want to display measurement data from linewidth measurements on a > silicon wafer.
