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.

◆ AddDirectoryStatus()

static bool RooPlot::AddDirectoryStatus ( )

inlinestatic

◆ addObject()

void RooPlot::addObject	(	TObject *	obj,
		Option_t *	drawOptions = `""`,
		bool	invisible = `false`
	)

Add a generic object to this plot.

The specified options will be used to Draw() this object later. The caller transfers ownership of the object with this call, and the object will be deleted when its containing plot object is destroyed.

Definition at line 380 of file RooPlot.cxx.

◆ addPlotable()

void RooPlot::addPlotable	(	RooPlotable *	plotable,
		Option_t *	drawOptions = `""`,
		bool	invisible = `false`,
		bool	refreshNorm = `false`
	)

Add the specified plotable object to our plot.

Increase our y-axis limits to fit this object if necessary. The default lower-limit is zero unless we are plotting an object that takes on negative values. This call transfers ownership of the plotable object to this class. The plotable object will be deleted when this plot object is deleted.

Definition at line 528 of file RooPlot.cxx.

◆ addTH1()

void RooPlot::addTH1	(	TH1 *	hist,

Add a TH1 histogram object to this plot.

The specified options will be used to Draw() this object later. "SAME" will be added to the options if they are not already present. The caller transfers ownership of the object with this call, and the object will be deleted when its containing plot object is destroyed.

◆ 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]	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.

◆ createInternalPlotVarClone()

void RooPlot::createInternalPlotVarClone ( )

Replaces the pointer to the plot variable with a pointer to a clone of the plot variable that is owned by this RooPlot.

The RooPlot references the plotted variable by non-owning pointer by default since ROOT 6.28, which resulted in a big speedup when plotting complicated pdfs that are expensive to clone. However, going back to an owned clone is useful in rare cases. For example in the RooUnitTest, where the registered plots need to live longer than the scope of the unit test.
