addBoundaryBins()

TH2F * ConfidenceContours::addBoundaryBins ( TH2F *  hist )

private

Helper function for computeContours(): Constructs a new 2D histogram that contains 2 more bins in each direction that are set to the minimum, so that the contours will always close.

Parameters

hist	- the 2D histogram

Returns

new 2D histogram. Caller assumes ownership.

Definition at line 65 of file ConfidenceContours.cpp.

addFilledPlotArea()

void ConfidenceContours::addFilledPlotArea ( TH2F *  hist )

private

Add a new contour that is just the plotted area.

Parameters

hist	- histogram providing the dimensions of the plotted area

Definition at line 115 of file ConfidenceContours.cpp.

computeContours()

void ConfidenceContours::computeContours	(	TH2F *	hist,
		histogramType	type,
		int	id = 0
	)

Compute the raw N sigma confidence contours from a 2D histogram holding either the chi2 or the p-value curve.

The resulting contours are stored into the m_contours member.

Parameters

hist	- the 2D histogram
type	- the type of the 2D histogram, either chi2 or p-value

Definition at line 144 of file ConfidenceContours.cpp.

Draw()

void ConfidenceContours::Draw

(

)

Draw the contours into the currently active Canvas.

Definition at line 246 of file ConfidenceContours.cpp.

DrawDashedLine()

void ConfidenceContours::DrawDashedLine

(

)

Draw the contours into the currently active Canvas.

Definition at line 260 of file ConfidenceContours.cpp.

setStyle()

void ConfidenceContours::setStyle	(	vector< int > &	linecolor,
		vector< int > &	linestyle,
		vector< int > &	fillcolor,
		vector< int > &	fillstyle
	)

Set the contour style.

Definition at line 273 of file ConfidenceContours.cpp.

setTransparency()

void ConfidenceContours::setTransparency ( float  percent )

inline

Definition at line 31 of file ConfidenceContours.h.

transformChi2valleyToHill()

TH2F * ConfidenceContours::transformChi2valleyToHill ( TH2F *  hist, float  offset  )

private

Helper function for computeContours(): Transforms the chi2 valley into a hill to help ROOTs contour mechanism Caller assumes ownership.

Parameters

hist	- the 2D histogram
offset	- a chi2 offset, usually 30 units

Returns

- the transformed 2D histogram
