Go4Fit
Class TGo4FitDataGraph

class TGo4FitDataGraph

derived from TGo4FitData

Data object, which provides access to TGraph and TGraphErrors ROOT objects.

TGraph is just N points with X and Y coordinates. This is mean, that it may be only one-dimensional.
The TGraph object can be assigned to TGo4FitDataGraph object in constructor, in SetGraph() method or in SetObject() method of fitter. TGraph object may owned, or may not owned by data object.
TGo4FitDataGraph gets Y values as bins containment. If no calibration object is sets up, X can be used as axis values.
If TGraphErrors object is assigned, the error values of Y can be used as sigmas in chi-square calculations (fit-function type should be ff_chi_square).
