NChartDataSmootherSpline Class Reference

Inherits from NChartDataSmoother : NSObject
Declared in NChartDataSmootherSpline.h


The NChartDataSmootherSpline class provides data smoother based on cubic defect 1 splines used to create smooth lines on the charts by only a few points. Typically this smoother is used for line and area series.

This smoother ensures the best smoothing in comparison with NChartDataSmootherTBezier and NChartDataSmootherSBezier, but has large deviation from the linear data interpolation and can produce large fake extremums.
