void TGo4Fitter::Draw ( Option_t *  option)
virtual

Draw fitter on current canvas. As options, data name(s) or component name(s) should be specified, separated by commas. For instance: Draw("data1") - draw data object with name "data1" and it's full model Draw("data1,Gauss1,Gauss2") - draw data object "data1", full model and model components with names "Gauss1" and "Gauss2" All objects is created via CreateDrawObject() method and stored in internal list. They will be moved to ROOT when fitter will be destroyed.

void TGo4Fitter::EstimateAmplitudes ( Int_t  NumIters = 1)

Estimate amplitude of all model components. This routine typically should be executed before general minimization routine. To obtain good estimation of amplitudes, rest model parameters (like position and widths) should has good estimation, otherwise amplitude estimation routine gives unacceptable values.
