NChartDataSmootherTBezier Class Reference

Inherits from NChartDataSmoother : NSObject
Declared in NChartDataSmootherTBezier.h


The NChartDataSmootherTBezier class provides data smoother based on bezier interpolation (with control points calculated according to tangents to the curve being smoothed) 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 minimal deviation from the linear data interpolation (in comparison with NChartDataSmootherSpline, NChartDataSmootherLagrange and NChartDataSmootherSBezier) and guarantees the absence of fake extremums.
