Class Description

RooCurve()
RooCurve(const RooAbsReal &f, RooAbsRealLValue &x, Double_t xlo, Double_t xhi, Int_t xbins, Double_t scaleFactor, const RooArgSet *normVars, Double_t prec, Double_t resolution, Bool_t shiftToZero, WingMode wmode)
 Create a 1-dim curve of the value of the specified real-valued expression
 as a function of x. Use the optional precision parameter to control
 how precisely the smooth curve is rasterized. Use the optional argument set
 to specify how the expression should be normalized. Use the optional scale
 factor to rescale the expression after normalization.
 If shiftToZero is set, the entire curve is shift down to make the lowest
 point in of the curve go through zero.
 grab the function's name and title
RooCurve(const char *name, const char *title, const RooAbsFunc &func, Double_t xlo, Double_t xhi, UInt_t minPoints, Double_t prec, Double_t resolution, Bool_t shiftToZero, WingMode wmode)
RooCurve(const char* name, const char* title, const RooCurve& c1, const RooCurve& c2, Double_t scale1, Double_t scale2)
~RooCurve()
void initialize()
 Perform initialization that is common to all constructors.
void shiftCurveToZero(Double_t prevYMax)
 Find lowest point in curve and move all points in curve so that
 lowest point will go exactly through zero
void addPoints(const RooAbsFunc &func, Double_t xlo, Double_t xhi, Int_t minPoints, Double_t prec, Double_t resolution, WingMode wmode)
 Add points calculated with the specified function, over the range (xlo,xhi).
 Add at least minPoints equally spaced points, and add sufficient points so that
 the maximum deviation from the final straight-line segements is prec*(ymax-ymin),
 down to a minimum horizontal spacing of resolution*(xhi-xlo).
 check the inputs
void addRange(const RooAbsFunc& func, Double_t x1, Double_t x2, Double_t y1, Double_t y2, Double_t minDy, Double_t minDx)
 Fill the range (x1,x2) with points calculated using func(&x). No point will
 be added at x1, and a point will always be added at x2. The density of points
 will be calculated so that the maximum deviation from a straight line
 approximation is prec*(ymax-ymin) down to the specified minimum horizontal spacing.
 calculate our value at the midpoint of this range
void addPoint(Double_t x, Double_t y)
 Add a point with the specified coordinates. Update our y-axis limits.
Double_t getFitRangeNEvt()
Double_t getFitRangeNEvt(Double_t, Double_t)
Double_t getFitRangeBinW()
void printToStream(ostream& os, PrintOption opt, TString indent)
 Print info about this histogram to the specified output stream.

   Standard: number of entries
    Verbose: print points on curve
Double_t chiSquare(const RooHist& hist, Int_t nFitParam)
Double_t average(Double_t xFirst, Double_t xLast)
 Average curve between given values by integrating curve between points
 and dividing by xLast-xFirst
Int_t findPoint(Double_t xvalue, Double_t tolerance)
Double_t interpolate(Double_t xvalue, Double_t tolerance)
 Find best point
