QwtCPointerData::QwtCPointerData(constdouble*x,constdouble*y,size_tsize)
       Constructor

       Parameters:x Array of x values
           y Array of y values
           size Size of the x and y arrays

       Warning:
           The programmer must assure that the memory blocks referenced by the pointers remain valid during the
           lifetime of the QwtPlotCPointer object.

QRectFQwtCPointerData::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>.

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

       Parameters:index Index

       Returns:
           Sample at position i

       Implements QwtSeriesData<QPointF>.

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

       Implements QwtSeriesData<QPointF>.

   constdouble*QwtCPointerData::xData()constReturns:
           Array of the x-values

   constdouble*QwtCPointerData::yData()constReturns:
           Array of the y-values
