Stacked Spline Area Charts
RadChart has been deprecated since Q3 2014 and is marked as obsolete as of the 2026 Q2 SP1 (v2026.2.708) release. This is the last release that includes the RadChart component — its source code will be removed from the assembly in the next release. We strongly recommend using RadHtmlChart, Telerik's modern client-side charting component. To transition from RadChart to RadHtmlChart, refer to the following migration articles:

The Stacked Spline Area chart is a variation of the Spline Area chart. The areas are stacked so that each series adjoins but does not overlap the preceding series. This contrasts with the Stacked Area chart where each series overlays the preceding series.
To create a simple vertical Stacked Spline Area Chart set the SeriesOrientation property to Vertical. Set the RadChart DefaultType property or ChartSeries.Type to StackedSplineArea. Create multiple chart series and add chart items with Y or X and Y values
To create a simple horizontal Stacked Spline Area Chart set the SeriesOrientation property to Horizontal. Set the RadChart DefaultType property or ChartSeries.Type to StackedSplineArea. Create multiple chart series and add chart items with Y or X and Y values
