Member Function Documentation

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

Parameters:
    points Series of data points

Returns:
    Curve points

Implements QwtCurveFitter.

  QwtSplineCurveFitter::FitMode QwtSplineCurveFitter::fitMode () const Returns:
    Mode representing a spline algorithm

See also:
    setFitMode()

  void QwtSplineCurveFitter::setFitMode (FitMode mode) Select the algorithm used for building the spline

Parameters:
    mode Mode representing a spline algorithm

See also:
    fitMode()

  void QwtSplineCurveFitter::setSplineSize (int splineSize) Assign a spline size ( has to be at least 10 points )

Parameters:
    splineSize Spline size

See also:
    splineSize()

  int QwtSplineCurveFitter::splineSize () const Returns:
    Spline size

See also:
    setSplineSize()
