		const char *	iTitle,
		Int_t	iDataType = `dtHistogram`,
		Bool_t	AddAmpl = `kFALSE`
	)

Creates TGo4FitData object with given name and title. Type of data (histogram or points) and usage of amplitude can be specified. TGo4FitData object should not be created directly. Implementation of this class like TGo4FitDataHistogram, TGo4FitDataGraph and so on should be used.

void TGo4FitData::ApplyRangesForModelMask	(	TGo4FitComponent *	model,

Exclude points from model according model range conditions. Primary range conditions defines for data. No any model, associated to this data, can exceed it's ranges. But not full data range can be used for explicit model evaluation. This functions fill model mask (array of chars) inside data range, where model should be evaluated. Can be used only after Initialize() method.
