Returns:

the generated array

get

public double get(int dimIndex,
                  int index)

Description copied from interface: DataSet

Gets the x value of the data point with the index i

Specified by:

get in interface DataSet

Parameters:

dimIndex - the dimension index (ie. '0' equals 'X', '1' equals 'Y')

index - data point index
