Go4Fit
Class TGo4FitDataHistogram

class TGo4FitDataHistogram

derived from TGo4FitData

Data objects, which provides access to generic TH1 ROOT histogram.

There are several implementations of TH1 for one, two and three-dimensional histogram. All of them inherited from TH1 class and supported in TGo4FitDataHistogram object.
The histogram can be assigned to TGo4FitDataHistogram object in constructor, in SetHistogram() method or in SetObject() method of fitter. Histogram may owned, or may not owned by data object.
TGo4FitDataHistogram gets from histogram number of dimensions and number of bins on each axis. The first and last bins on each axis (0 and NBins+1 indexes) are excluded from data analysis. This means, that data object uses only bins, which has indexes from 1 to NBins.
If no calibration objects are sets up, TGo4FitDataHistogram can uses axis values, taken from histogram itself. As axis values central position of each bin is using.

public TGo4FitDataHistogram()

Default constructor.

public TGo4FitDataHistogram(const char * iName, TH1* , Bool_t iHistogramOwned, Bool_t AddAmpl)

Creates TGo4FitDataHistogram object with provided name.
Pointer on histogram (derived from TH1 class) and ownership flag can be sets up in constructor.
Scaling factor for bins (amplitude) can be added.

public virtual synchronized ~TGo4FitDataHistogram()

Destroys TGo4FitDataHistogram object.

public virtual void FillSlotList(TSeqCollection* list)

Add pointer on slot, which should contains histogram, to list.

public TH1* GetHistogram()

Return pointer on assigned histogram.

public TGo4FitDataIter* MakeIter()
