       Constructor

       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]
       Return a pointer to a copy (virtual copy constructor)

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

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

       Parameters:
