Member Function Documentation

   QRectF QwtPointArrayData::boundingRect () const [virtual]
       Calculate the bounding rect. 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_ti) const [virtual] Return the sample at position i
       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
