RooDataHist Class Reference

The RooDataHist is a container class to hold N-dimensional binned data.

Each bin's central coordinates in N-dimensional space are represented by a RooArgSet containing RooRealVar, RooCategory or RooStringVar objects, thus data can be binned in real and/or discrete dimensions.

Constructor & Destructor Documentation

◆ RooDataHist() [1/9]

RooDataHist::RooDataHist ( )

Default constructor.

Definition at line 66 of file RooDataHist.cxx.

◆ RooDataHist() [2/9]

RooDataHist::RooDataHist ( const char *  name,
const char *  title,
const RooArgSet vars,
const char *  binningName = 0 
)

Constructor of an empty data hist from a RooArgSet defining the dimensions of the data space.

The range and number of bins in each dimensions are taken from getMin()getMax(),getBins() of each RooAbsArg representing that dimension.

For real dimensions, the fit range and number of bins can be set independently of the plot range and number of bins, but it is advisable to keep the ratio of the plot bin width and the fit bin width an integer value. For category dimensions, the fit ranges always comprises all defined states and each state is always has its individual bin

To effective achive binning of real dimensions with variable bins sizes, construct a RooThresholdCategory of the real dimension to be binned variably. Set the thresholds at the desired bin boundaries, and construct the data hist as function of the threshold category instead of the real variable.

Definition at line 105 of file RooDataHist.cxx.

RooDataHist::RooDataHist ( const char *  name,
const char *  title,
const RooArgSet vars,
const RooAbsData data,
Double_t  wgt = 1.0 
)

Constructor of a data hist from an existing data collection (binned or unbinned) The RooArgSet 'vars' defines the dimensions of the histogram.

The range and number of bins in each dimensions are taken from getMin(), getMax(), getBins() of each argument passed.

For real dimensions, the fit range and number of bins can be set independently of the plot range and number of bins, but it is advisable to keep the ratio of the plot bin width and the fit bin width an integer value. For category dimensions, the fit ranges always comprises all defined states and each state is always has its individual bin

To effective achive binning of real dimensions with variable bins sizes, construct a RooThresholdCategory of the real dimension to be binned variably. Set the thresholds at the desired bin boundaries, and construct the data hist as function of the threshold category instead of the real variable.

If the constructed data hist has less dimensions that in source data collection, all missing dimensions will be projected.

Constructor of a data hist from a map of TH1,TH2 or TH3 that are collated into a x+1 dimensional RooDataHist where the added dimension is a category that labels the input source as defined in the histMap argument.

The state names used in histMap must correspond to predefined states 'indexCat'

const RooCmdArg arg7 = RooCmdArg(),
const RooCmdArg arg8 = RooCmdArg() 
)

Constructor of a binned dataset from a RooArgSet defining the dimensions of the data space.

The range and number of bins in each dimensions are taken from getMin() getMax(),getBins() of each RooAbsArg representing that dimension.

Optional Argument Effect
Import(TH1&, Bool_t impDens)

Import contents of the given TH1/2/3 into this binned dataset. The ranges and binning of the binned dataset are automatically adjusted to match those of the imported histogram.

Please note: for TH1& with unequal binning only, you should decide if you want to import the absolute bin content, or the bin content expressed as density. The latter is default and will result in the same histogram as the original TH1. For certain types of bin contents (containing efficiencies, asymmetries, or ratio is general) you should import the absolute value and set impDens to kFALSE

Weight(Double_t)

Apply given weight factor when importing histograms

Index(RooCategory&)

Prepare import of multiple TH1/1/2/3 into a N+1 dimensional RooDataHist where the extra discrete dimension labels the source of the imported histogram If the index category defines states for which no histogram is be imported the corresponding bins will be left empty.

Import(const char*, TH1&) Import a THx to be associated with the given state name of the index category specified in Index(). If the given state name is not yet defined in the index category it will be added on the fly. The import command can be specified multiple times.
Import(map<string,TH1*>&) As above, but allows specification of many imports in a single operation

Constructor of a data hist from (part of) an existing data hist.

The dimensions of the data set are defined by the 'vars' RooArgSet, which can be identical to 'dset' dimensions, or a subset thereof. Reduced dimensions will be projected in the output data hist. The optional 'cutVar' formula variable can used to select the subset of bins to be copied.

For most uses the RooAbsData::reduce() wrapper function, which uses this constructor, is the most convenient way to create a subset of an existing data

  • Auto(default) results in Poisson for unweighted data and SumW2 for weighted data
  • Poisson draws asymmetric Poisson confidence intervals.
  • SumW2 draws symmetric sum-of-weights error ( \( \left( \sum w \right)^2 / \sum\left(w^2\right) \) )
  • None draws no error bars
Binning(int nbins, double xlo, double xhi) Use specified binning to draw dataset
Binning(const RooAbsBinning&) Use specified binning to draw dataset
Binning(const char* name) Use binning with specified name to draw dataset
RefreshNorm(Bool_t flag) Force refreshing for PDF normalization information in frame. If set, any subsequent PDF will normalize to this dataset, even if it is not the first one added to the frame. By default only the 1st dataset added to a frame will update the normalization information
Rescale(Double_t f) Rescale drawn histogram by given factor.
Cut(const char*)

Only plot entries that pass the given cut. Apart from cutting in continuous variables Cut("x>5"), this can also be used to plot a specific category state. Use something like Cut("myCategory == myCategory::stateA"), where myCategory resolves to the state number for a given entry and myCategory::stateA resolves to the state number of the state named "stateA".

CutRange(const char*) Only plot data from given range. Separate multiple ranges with ",".
Note
This often requires passing the normalisation when plotting the PDF because RooFit does not save how many events were being plotted (it will only work for cutting slices out of uniformly distributed variables).
data->plotOn(frame01, CutRange("SB1"));
const double nData = data->sumEntries("", "SB1");
// Make clear that the target normalisation is nData. The enumerator NumEvent
// is needed to switch between relative and absolute scaling.
model.plotOn(frame01, Normalization(nData, RooAbsReal::NumEvent),
ProjectionRange("SB1"));
Histogram drawing options
DrawOption(const char* opt) Select ROOT draw option for resulting TGraph object
LineStyle(Int_t style) Select line style by ROOT line style code, default is solid
LineColor(Int_t color) Select line color by ROOT color code, default is black
LineWidth(Int_t width) Select line with in pixels, default is 3
MarkerStyle(Int_t style) Select the ROOT marker style, default is 21
MarkerColor(Int_t color) Select the ROOT marker color, default is black
MarkerSize(Double_t size) Select the ROOT marker size
FillStyle(Int_t style) Select fill style, default is filled.
FillColor(Int_t color) Select fill color by ROOT color code
XErrorSize(Double_t frac)

Select size of X error bar as fraction of the bin width, default is 1

Misc. other options
Name(const chat* name) Give curve specified name in frame. Useful if curve is to be referenced later
Invisible() Add curve to frame, but do not display. Useful in combination AddTo()
AddTo(const char* name, double_t wgtSelf, double_t wgtOther) Add constructed histogram to already existing histogram with given name and relative weight factors

◆ plotOn() [3/4]

RooPlot * RooAbsData::plotOn

Create and fill a histogram of the frame's variable and append it to the frame.

The frame variable must be one of the data sets dimensions.

The plot range and the number of plot bins is determined by the parameters of the plot variable of the frame (RooAbsReal::setPlotRange(), RooAbsReal::setPlotBins()).

The optional cut string expression can be used to select the events to be plotted. The cut specification may refer to any variable contained in the data set.

The drawOptions are passed to the TH1::Draw() method.
