Detailed Description
       A curve fitter using a spline interpolation.

       The default setting for the spline is a cardinal spline with uniform
       parametrization.

Member Function Documentation
   QPolygonF QwtSplineCurveFitter::fitCurve (const QPolygonF & points) const
       [override],  [virtual]
       Find a curve which has the best fit to a series of data points

       Parameters
           points Series of data points

       Returns
           Fitted Curve

   QPainterPath QwtSplineCurveFitter::fitCurvePath (const QPolygonF & points)
       const [override],  [virtual]
       Find a curve path which has the best fit to a series of data points

       Parameters
           points Series of data points

       Returns
           Fitted Curve

   void QwtSplineCurveFitter::setSpline (QwtSpline * spline)
       Assign a spline

       The spline needs to be allocated by new and will be deleted in the
       destructor of the fitter.

       Parameters
           spline Spline
