Add objects to a 2D plot that represent the fit results for the two named parameters.

The input frame with the objects added is returned, or zero in case of an error. Which objects are added are determined by the options string which should be a concatenation of the following (not case sensitive):

M - a marker at the best fit result E - an error ellipse calculated at 1-sigma using the error matrix at the minimum 1 - the 1-sigma error bar for parameter 1 2 - the 1-sigma error bar for parameter 2 B - the bounding box for the error ellipse H - a line and horizontal axis for reading off the correlation coefficient V - a line and vertical axis for reading off the correlation coefficient A - draw axes for reading off the correlation coefficients with the H or V options

You can change the attributes of objects in the returned RooPlot using the various RooPlot::getAttXxx(name) member functions, e.g.

plot->getAttLine("contour")->SetLineStyle(kDashed);

Use plot->Print() for a list of all objects and their names (unfortunately most of the ROOT builtin graphics objects like TLine are unnamed). Drag the left mouse button along the labels of either axis button to interactively zoom in a plot.

void RooFitResult::printArgs ( std::ostream & os ) const

virtual

Print arguments of fit result, i.e. the parameters of the fit.

Reimplemented from RooPrintable.

Definition at line 1402 of file RooFitResult.cxx.

◆ printClassName()

void RooFitResult::printClassName ( std::ostream & os ) const

virtual

Print class name of fit result.

Reimplemented from RooPrintable.

Definition at line 1393 of file RooFitResult.cxx.

◆ printMultiline()

void RooFitResult::printMultiline	(	std::ostream &	os,
		Int_t	contents,
		Bool_t	verbose = `kFALSE`,
		TString	indent = `""`
	)		const

virtual

Print fit result to stream 'os'.

In Verbose mode, the contant parameters and the initial and final values of the floating parameters are printed. Standard mode only the final values of the floating parameters are printed

Reimplemented from RooPrintable.

Definition at line 501 of file RooFitResult.cxx.

◆ printName()

void RooFitResult::printName ( std::ostream & os ) const

virtual

Print name of fit result.

Reimplemented from RooPrintable.

Definition at line 1375 of file RooFitResult.cxx.

◆ printTitle()

void RooFitResult::printTitle ( std::ostream & os ) const

virtual

Print title of fit result.

Reimplemented from RooPrintable.

Definition at line 1384 of file RooFitResult.cxx.

◆ printValue()

void RooFitResult::printValue ( std::ostream & os ) const

virtual

Print the value of the fit result, i.e.g the status, minimized FCN, edm and covariance quality code.

Reimplemented from RooPrintable.

Definition at line 1412 of file RooFitResult.cxx.

◆ randomizePars()

const RooArgList & RooFitResult::randomizePars ( ) const

Return a list of floating parameter values that are perturbed from the final fit values by random amounts sampled from the covariance matrix.

The returned object is overwritten with each call and belongs to the RooFitResult. Uses the "square root method" to decompose the covariance matrix, which makes inverting it unnecessary.

Definition at line 346 of file RooFitResult.cxx.

◆ reducedCovarianceMatrix()

TMatrixDSym RooFitResult::reducedCovarianceMatrix ( const RooArgList & params ) const

Return a reduced covariance matrix (Note that Vred is a simple sub-matrix of V, row/columns are ordered to matched the convention given in input argument 'params'.
