Class describing the binned data sets : vectors of x coordinates, y values and optionally error on y values and error on coordinates The dimension of the coordinate is free There are 4 different options:

only coordinates and values (for binned likelihood fits) : kNoError
coordinate, values and error on values (for normal least square fits) : kValueError
coordinate, values, error on values and coordinates (for effective least square fits) : kCoordError
coordinate, values, error on coordinates and asymmetric error on values : kAsymError

In addition there is the option to construct Bindata copying the data in (using the DataVector class) or using pointer to external data (DataWrapper) class. In general is found to be more efficient to copy the data. In case of really large data sets for limiting memory consumption then the other option can be used Specialized constructor exists for data up to 3 dimensions.

When the data are copying in the number of points can be set later (or re-set) using Initialize and the data are inserted one by one using the Add method. It is mandatory to set the size before using the Add method.

◆ fCoords

std::vector< std::vector< double > > ROOT::Fit::FitData::fCoords

privateinherited

This vector stores the vectorizable data: The inner vectors contain the coordinates data fCoords[0] is the vector for the x-coords fCoords[1] is the vector for the y-coords etc.

The vector of pointers stores the pointers to the first elements of the corresponding elements

If fWrapped is true, fCoords is empty. the data can only be accessed by using fCoordsPtr.
