Member Function Documentation

   QRectF QwtPointArrayData::boundingRect () const [virtual]
       Calculate the bounding rectangle. The bounding rectangle is calculated once by iterating
       over all points and is stored for all following requests.

       Returns:
           Bounding rectangle

       Implements QwtSeriesData< QPointF >.

   QPointF QwtPointArrayData::sample (size_tindex) const [virtual]
       Return the sample at position i

       Parameters:
           index 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
