RooDataSet is a container class to hold unbinned data.
A RooHist is a graphical representation of binned data based on the TGraphAsymmErrors class.
A RooPlot is a plot frame and a container for graphics objects within that frame.
RooHist * residHist(const char *histname=0, const char *pdfname=0, bool normalize=false, bool useAverage=true) const
Return a RooHist (derives from TGraphAsymErrors) containing the residuals of a histogram.
Double_t chiSquare(int nFitParam=0) const
Shortcut for RooPlot::chiSquare(const char* pdfname, const char* histname, int nFitParam=0)
static RooPlot * frame(const RooAbsRealLValue &var, Double_t xmin, Double_t xmax, Int_t nBins)
Create a new frame for a given variable in x.
void addPlotable(RooPlotable *plotable, Option_t *drawOptions="", Bool_t invisible=kFALSE, Bool_t refreshNorm=kFALSE)
Add the specified plotable object to our plot.
virtual void Draw(Option_t *options=0)
Draw this plot and all of the elements it contains.
RooHist * pullHist(const char *histname=0, const char *pdfname=0, bool useAverage=true) const
Uses residHist() and sets normalize=true.
RooRealVar represents a variable that can be changed from the outside.
virtual void SetTitleOffset(Float_t offset=1)
Set distance between the axis and the axis title.
The namespace RooFit contains mostly switches that change the behaviour of functions of PDFs (or othe...
