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

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

◆ 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.

	)

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 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.

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

	)

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.

This constructor takes the following optional arguments

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 type 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

RooPlot * RooAbsData::plotOn	(	RooPlot *	frame,

	)		const

virtual

Plot dataset on specified frame.

By default an unbinned dataset will use the default binning of the target frame. A binned dataset will by default retain its intrinsic binning.

The following optional named arguments can be used to modify the default behavior

	Data representation options
`Asymmetry(const RooCategory& c)`	Show the asymmetry of the data in given two-state category [F(+)-F(-)] / [F(+)+F(-)]. Category must have two states with indices -1 and +1 or three states with indices -1,0 and +1.
`Efficiency(const RooCategory& c)`	Show the efficiency F(acc)/[F(acc)+F(rej)]. Category must have two states with indices 0 and 1
`DataError(RooAbsData::EType)`	Select the type of error drawn: `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 ( sum(w)^2/sum(w^2) ) `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
	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

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
