Detailed Description
       Data class containing two pointers to memory blocks of doubles.

Constructor &; Destructor Documentation
   QwtCPointerData::QwtCPointerData (const double *x, const double *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.

Member Function Documentation
   QwtDoubleRect QwtCPointerData::boundingRect () const [virtual] Returns the bounding rectangle of the data. If there is no bounding rect, like
       for empty data the rectangle is invalid: QwtDoubleRect::isValid() == false
       Reimplemented from QwtData.

   QwtData * QwtCPointerData::copy () const [virtual] Returns:
	   Pointer to a copy (virtual copy constructor)

       Implements QwtData.

   QwtCPointerData & QwtCPointerData::operator= (const QwtCPointerData &data)
       Assignment.

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

       Implements QwtData.

   double QwtCPointerData::x (size_ti) const [virtual] Return the x value of data point i
       Parameters:
	   i Index

       Returns:
	   x X value of data point i

       Implements QwtData.

   const double * QwtCPointerData::xData () const Returns:
	   Array of the x-values

   double QwtCPointerData::y (size_ti) const [virtual] Return the y value of data point i
       Parameters:
	   i Index

       Returns:
	   y Y value of data point i

       Implements QwtData.

   const double * QwtCPointerData::yData () const Returns:
	   Array of the y-values
