Hi,
I'm seeing strange (i.e. bad) behavior when using an array to pass to the
TH1F constructor.
If I do the following:
const int nbins_eEta=3;
float eEta[nbins_eEta]={-5.0,-2.5,-0.1};
TH1F* histo = new TH1F("h_ElectronEta_","ElectronEta_"),nbins_eEta,eEta);
I get no error, but I do notice that the histogram ends at 0, i.e. the last bin is [-0.1,0]. Otherwise it works.
If I try to go positive, i.e.
const int nbins_eEta=4;
float eEta[nbins_eEta]={-5.0,-2.5,-0.1,0.1};
I get the following errors:
init histosError in <TAxis::TAxis::Set>: bins must be in increasing order
Error in <TAxis::TAxis::Set>: bins must be in increasing order
I suppose I'm doing something wrong in the initialization. Any ideas?
Thanks,
Adam
