NChartDataSmootherSBezier Class Reference

Inherits from NChartDataSmoother : NSObject
Declared in NChartDataSmootherSBezier.h


The NChartDataSmootherSBezier class provides data smoother based on bezier interpolation (with control points calculated to ensure defect 1 spline) 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 better smoothing in comparison with NChartDataSmootherTBezier, but has larger deviation from the linear data interpolation and can produce fake extremums. However, the deviation of the fake extremums is smaller in comparison with NChartDataSmootherSpline and NChartDataSmootherLagrange.
