Member Function Documentation
   QwtArray< QwtDoubleInterval > QwtClipper::clipCircle (const QwtDoubleRect &clipRect, const QwtDoublePoint &center, doubleradius) [static]
       Circle clipping
       clipCircle() devides a circle into intervals of angles representing arcs of the circle. When the circle is completely inside the clip
       rectangle an interval [0.0, 2 * M_PI] is returned.

       Parameters:
	   clipRect Clip rectangle
	   center Center of the circle
	   radius Radius of the circle

       Returns:
	   Arcs of the circle

   QwtPolygon QwtClipper::clipPolygon (const QRect &clipRect, const QwtPolygon &polygon) [static] Sutherland-Hodgman polygon clipping
       Parameters:
	   clipRect Clip rectangle
	   polygon Polygon

       Returns:
	   Clipped polygon

   QwtPolygonF QwtClipper::clipPolygonF (const QwtDoubleRect &clipRect, const QwtPolygonF &polygon) [static] Sutherland-Hodgman polygon clipping
       Parameters:
	   clipRect Clip rectangle
	   polygon Polygon

       Returns:
	   Clipped polygon

Constructor &; Destructor Documentation
   QwtArrayData::QwtArrayData (const QwtArray< double > &x, const QwtArray< double > &y) Constructor
       Parameters:
	   x Array of x values
	   y Array of y values

       See also:
	   QwtPlotCurve::setData()

   QwtArrayData::QwtArrayData (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

       See also:
	   QwtPlotCurve::setData()

Member Function Documentation
   QwtDoubleRect QwtArrayData::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 * QwtArrayData::copy () const [virtual] Returns:
	   Pointer to a copy (virtual copy constructor)

       Implements QwtData.

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

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

       Implements QwtData.

   double QwtArrayData::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 QwtArray< double > & QwtArrayData::xData () const Returns:
	   Array of the x-values

   double QwtArrayData::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 QwtArray< double > & QwtArrayData::yData () const Returns:
	   Array of the y-values
