Spline

The Spline series is a point-line series with an automatic polynomial interpolation that produces smooth curves.

// Creation of a spline series
const splineSeries = chart.addSplineSeries()

For "points" oriented guides, please refer to Scatter section.

Otherwise, the spline series functions exactly same as a Line series.

Spline area series can be realized by using functions from Area series.

tip

Spline series are actually PointLineAreaSeries with suitable default settings applied. Spline can be enabled with setCurvePreprocessing method.
