Spline Range Area

The Spline Range Area Chart is used to display continuous data points as a set of splines that vary between high and low values over intervals of time and across different categories.

To render a spline range area series, use series type as SplineRangeArea and inject SplineRangeAreaSeries module using Chart.Inject(SplineRangeAreaSeries) method.
