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

See also

fitCurvePath()

Implements QwtCurveFitter.

Definition at line 75 of file qwt_spline_curve_fitter.cpp.

QPainterPath QwtSplineCurveFitter::fitCurvePath (const QPolygonF & points)const [override], [virtual]
