RooAbsData Class Referenceabstract

RooAbsData is the common abstract base class for binned and unbinned datasets.

The abstract interface defines plotting and tabulating entry points for its contents and provides an iterator over its elements (bins for binned data sets, data points for unbinned datasets).

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
CutRange(const char*) Apply cuts to dataset.
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

Add a box with statistics information to the specified frame.

By default a box with the event count, mean and rms of the plotted variable is added.

The following optional named arguments are accepted

What(const char* whatstr) Controls what is printed: "N" = count, "M" is mean, "R" is RMS.
Format(const char* optStr)
Deprecated:
Classing parameter formatting options, provided for backward compatibility

Format(const char* what,...) Parameter formatting options.
const char* what Controls what is shown:
  • "N" adds name
  • "E" adds error
  • "A" shows asymmetric error
  • "U" shows unit
  • "H" hides the value
FixedPrecision(int n) Controls precision, set fixed number of digits
AutoPrecision(int n) Controls precision. Number of shown digits is calculated from error + n specified additional digits (1 is sensible default)
VerbatimName(Bool_t flag) Put variable name in a \verb+ + clause.
Label(const chat* label) Add header label to parameter box
Layout(Double_t xmin, Double_t xmax, Double_t ymax) Specify relative position of left,right side of box and top of box. Position of bottom of box is calculated automatically from number lines in box
Cut(const char* expression) Apply given cut expression to data when calculating statistics
CutRange(const char* rangeName)

Only consider events within given range when calculating statistics. Multiple CutRange() argument may be specified to combine ranges.

virtual

Create and fill a 1-dimensional table for given category column This functions is the equivalent of plotOn() for category dimensions.

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

The option string is currently not used

◆ tree()

const TTree * RooAbsData::tree ( ) const

Return a pointer to the TTree which stores the data.

Returns a nullpointer if vector-based storage is used. The RooAbsData remains owner of the tree. GetClonedTree() can be used to get a tree even if the internal storage does not use one.
