Class Description

   A TGraph2DErrors is a TGraph2D with errors.


TGraph2DErrors(): TGraph2D()
 TGraph2DErrors default constructor

TGraph2DErrors(Int_t n) : TGraph2D(n)
 TGraph2DErrors normal constructor
 the arrays are preset to zero

TGraph2DErrors(Int_t n, Double_t *x, Double_t *y, Double_t *z, Double_t *ex, Double_t *ey, Double_t *ez, Option_t *) :TGraph2D(n, x, y, z)
 TGraph2DErrors constructor with doubles vectors as input.

~TGraph2DErrors()
 TGraph2DErrors destructor.

Double_t GetErrorX(Int_t i) const
 This function is called by Graph2DFitChisquare.
 It returns the error along X at point i.

Double_t GetErrorY(Int_t i) const
 This function is called by Graph2DFitChisquare.
 It returns the error along X at point i.

Double_t GetErrorZ(Int_t i) const
 This function is called by Graph2DFitChisquare.
 It returns the error along X at point i.

void SetPoint(Int_t i, Double_t x, Double_t y, Double_t z)
 Set x, y and z values for point number i

void SetPointError(Int_t i, Double_t ex, Double_t ey, Double_t ez)
 Set ex, ey and ez values for point number i

void Streamer(TBuffer &b)
 Stream an object of class TGraphErrors.
