Spline
Documentation
Spline series types, like line series types, help visualize data trends over specified intervals. However, splines help «smooth» individual lines that connect data points. In this example, you can switch between the spline, stacked spline and full-stacked spline series types. Stacked spline series help visualize multiple series and compare the manner in which each series contributes to the total aggregate value for specific arguments. Full-stacked spline series help compare the percentage value of multiple spline series for each argument.
