Hi,
I have a
Double_t x[5] = { 0, 1, 2, 3, 4 };
TH3D fHist("", "", 4, x, 4, x, 4, x);
and do:
fHist.GetZaxis()->SetRange(3, 4);
TH1 *h2 = fHist.Project3D("xy_off"); //, -1, 9999, "E");
fHist.GetZaxis()->SetRange(1,2);
TH1 *h3 = fHist.Project3D("xy_on"); //, -1, 9999, "E");
TH2D *h4 = new TH2D;
h4->Divide(h3, h2);
And I get
Attempt to divide histograms with different number of bins...
What am I doing wrong? I would expect to have two projections to have
the same binning...
Thomas.
