Spline Area

API Reference
Spline Area chart series types, like area series types, are used to clearly emphasize change in values displayed within a chart. However, spline area series help “smooth” individual lines that connect data points. In this example, you can switch between a splineArea, stackedSplineArea and fullStackedSplineArea series types. The stacked series types help visualize multiple series and compare the manner in which each series contributes to the total aggregate value for specific arguments. The Full Stacked Spline Area chart series helps compare the percentage value of multiple spline area series for each argument.
