MetHists

class MetHists

Inherits from HistogramManager

Public Functions

MetHists(std::string name, std::string detailStr)
~MetHists()
StatusCode initialize()

Initialize and book all histograms.

Note

This should call the overloaded functions HistogramManager::book() to create the histograms so that the user can call hists->record(wk()) to record all histograms to the EventLoop worker.

Example implementation:

StatusCode JetHists::initialize() {
  m_jetPt          = book(m_name, "jetPt",  "jet p_{T} [GeV]", 120, 0, 3000.);
  return StatusCode::SUCCESS;
}

StatusCode execute(const xAOD::MissingETContainer *met, float eventWeight)
virtual StatusCode execute()

Execute by filling in the histograms.

Example implementation:

StatusCode JetHists::execute( const xAOD::JetContainer* jets, float eventWeight ){
  for(const auto& jet: *jets)
    m_jetPt->Fill( jet->pt()/1.e3, eventWeight );
  return StatusCode::SUCCESS;
}

virtual StatusCode finalize()

Finalize anything that needs to be finalized.

Warning

This should rarely be used. There is not a good use case for this functionality but it needs to exist in the off-chance that a user comes along and needs it for their histogram class.

TH1F *book(std::string name, std::string title, std::string xlabel, int xbins, double xlow, double xhigh)

record a histogram and call various functions

Note
This is an overloaded function. It will build the right histogram given the correct number of input arguments.
Parameters
  • name: name of histogram, access it in ROOT file like h_jetPt->Draw()
  • title: usually pointless,put a description of the histogram in here
  • xlabel: label to put on the x-axis
  • xbins: number of xbins to use
  • xlow: lower bound on xbins
  • xhigh: upper bound on xbins
  • xbinsArr: variable xbins, test math \((x_1,y_1)\) and \((x_2,y_2)\)
  • ylabel: label to put on the y-axis
  • ylow: lower bound on ybins
  • yhigh: upper bound on ybins
  • ybinsArr: variable ybins
  • zlabel: label to put on the z-axix
  • zlow: lower bound on zbins
  • zhigh: upper bound on zbins
  • zbinsArr: variable zbins
