       Parameters:
	   i Index

       Returns:
	   Sample at position i

       Implements QwtSeriesData< QPointF >.

   size_t QwtPointArrayData::size () const [virtual] Returns:
	   Size of the data set

       Implements QwtSeriesData< QPointF >.

   const QVector< double > & QwtPointArrayData::xData () const Returns:
	   Array of the x-values

   const QVector< double > & QwtPointArrayData::yData () const Returns:
	   Array of the y-values
