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) ;

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.

◆ chiSquare() [1/2]

Double_t 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]	curvename	Name of the curve or nullptr for last curve
[in]	histname	Name of the histogram to compare to or nullptr for last added histogram
[in]	nFitParam	If 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.
