RooDataSet is a container class to hold unbinned data.
Single or double sided decay function that can be analytically convolved with any RooResolutionModel ...
Class RooGaussModel implements a RooResolutionModel that models a Gaussian distribution.
Landau distribution p.d.f.
A RooPlot is a plot frame and a container for graphics objects within that frame.
static RooPlot * frame(const RooAbsRealLValue &var, double xmin, double xmax, Int_t nBins)
Create a new frame for a given variable in x.
void Draw(Option_t *options=nullptr) override
Draw this plot and all of the elements it contains.
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.
virtual void SetLineColor(Color_t lcolor)
Set the line color.
TH1 is the base class of all histogram classes in ROOT.
void Draw(Option_t *option="") override
Draw this histogram with options.
