Constructor & Destructor Documentation

◆ RooHist() [1/6]

RooHist::RooHist ( )

Default constructor.

Definition at line 50 of file RooHist.cxx.

◆ RooHist() [2/6]

RooHist::RooHist ( Double_t  nominalBinWidth,
Double_t  nSigma = 1,
Double_t  xErrorFrac = 1.0,
Double_t  scaleFactor = 1.0 
)

Create an empty histogram that can be filled with the addBin() and addAsymmetryBin() methods.

Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addBin(), and is used to set the relative normalization of bins with different widths.

Definition at line 68 of file RooHist.cxx.

◆ RooHist() [3/6]

RooHist::RooHist ( const TH1 data,
Double_t  nominalBinWidth = 0,
Double_t  nSigma = 1,
RooAbsData::ErrorType  etype = RooAbsData::Poisson,
Double_t  xErrorFrac = 1.0,
Bool_t  correctForBinWidth = kTRUE,
Double_t  scaleFactor = 1. 
)

Create a histogram from the contents of the specified TH1 object which may have fixed or variable bin widths.

Error bars are calculated using Poisson statistics. Prints a warning and rounds any bins with non-integer contents. Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addBin(), and is used to set the relative normalization of bins with different widths. If not set, the nominal bin width is calculated as range/nbins.

Definition at line 86 of file RooHist.cxx.

◆ RooHist() [4/6]

RooHist::RooHist ( const TH1 data1,
const TH1 data2,
Double_t  nominalBinWidth = 0,
Double_t  nSigma = 1,
RooAbsData::ErrorType  etype = RooAbsData::Poisson,
Double_t  xErrorFrac = 1.0,
Bool_t  efficiency = kFALSE,
Double_t  scaleFactor = 1.0 
)

Create a histogram from the asymmetry between the specified TH1 objects which may have fixed or variable bin widths, but which must both have the same binning.

The asymmetry is calculated as (1-2)/(1+2). Error bars are calculated using Binomial statistics. Prints a warning and rounds any bins with non-integer contents. Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addAsymmetryBin(), and is used to set the relative normalization of bins with different widths. If not set, the nominal bin width is calculated as range/nbins.

Definition at line 133 of file RooHist.cxx.

◆ RooHist() [5/6]

RooHist::RooHist ( const RooHist hist1,
const RooHist hist2,
Double_t  wgt1 = 1.0,
Double_t  wgt2 = 1.0,
RooAbsData::ErrorType  etype = RooAbsData::Poisson,
Double_t  xErrorFrac = 1.0 
)

Create histogram as sum of two existing histograms.

If Poisson errors are selected the histograms are added and Poisson confidence intervals are calculated for the summed content. If wgt1 and wgt2 are not 1 in this mode, a warning message is printed. If SumW2 errors are selected the histograms are added and the histograms errors are added in quadrature, taking the weights into account.

Definition at line 206 of file RooHist.cxx.

◆ RooHist() [6/6]

RooHist::RooHist ( const RooAbsReal f,
RooAbsRealLValue x,
Double_t  xErrorFrac = 1.0,
Double_t  scaleFactor = 1.0,
const RooArgSet normVars = 0,
const RooFitResult fr = 0 
)

Create histogram from a pdf or function.

Errors are computed based on the fit result provided.

This signature is intended for unfolding/deconvolution scenarios, where a pdf is constructed as "data minus background" and is thus intended to be displayed as "data" (or at least data-like). Usage of this signature is triggered by the draw style "P" in RooAbsReal::plotOn.

More details.

Parameters
[in]fThe function to be plotted.
[in]xThe variable on the x-axis
[in]xErrorFracSize of the errror in x as a fraction of the bin width
[in]scaleFactorarbitrary scaling of the y-values
[in]normVarsvariables over which to normalize
