RooPlot Class Reference

A RooPlot is a plot frame and a container for graphics objects within that frame.

As a frame, it provides the TH1-style public interface for setting plot ranges, configuring axes, etc. As a container, it holds an arbitrary set of objects that might be histograms of data, curves representing a fit model, or text labels. Use the Draw() method to draw a frame and the objects it contains. Use the various add...() methods to add objects to be drawn. In general, the add...() methods create a private copy of the object you pass them and return a pointer to this copy. The caller owns the input object and this class owns the returned object. All RooAbsReal and RooAbsData derived classes implement plotOn() functions that facilitate to plot themselves on a given RooPlot, e.g.

RooPlot *frame = x.frame() ;
data.plotOn(frame) ;
pdf.plotOn(frame) ;
Option_t Option_t TPoint TPoint const char GetTextMagnitude GetFillStyle GetLineColor GetLineWidth GetMarkerStyle GetTextAlign GetTextColor GetTextSize void data
A RooPlot is a plot frame and a container for graphics objects within that frame.
Definition: RooPlot.h:43
static RooPlot * frame(const RooAbsRealLValue &var, double xmin, double xmax, Int_t nBins)
Create a new frame for a given variable in x.
Definition: RooPlot.cxx:239
Double_t x[n]
Definition: legend1.C:17

These high level functions also take care of any projections or other mappings that need to be made to plot a multi-dimensional object onto a one-dimensional plot.

)

Add a generic object to this plot.

◆ chiSquare() [1/2]

double RooPlot::chiSquare ( const char *  curvename,
const char *  histname,
int  nFitParam = 0 
) const

Calculate and return reduced chi-squared between a curve and a histogram.

Parameters
[in]curvenameName of the curve or nullptr for last curve
[in]histnameName of the histogram to compare to or nullptr for last added histogram
[in]nFitParamIf non-zero, reduce the number of degrees of freedom by this number. This means that the curve was fitted to the data with nFitParam floating parameters, which needs to be reflected in the calculation of \(\chi^2 / \mathrm{ndf}\).
Returns
\( \chi^2 / \mathrm{ndf} \) between the plotted curve and the data.
Note
The \( \chi^2 \) is calculated between a plot of the original distribution and the data. It therefore has more rounding errors than directly calculating the \( \chi^2 \) from a PDF or function. To do this, use RooChi2Var.

Definition at line 1080 of file RooPlot.cxx.

◆ chiSquare() [2/2]
