Stacked Spline Area

Stacked spline area series plot data regions as vertically stacked bands to visualize cumulative values (you must add more than one series of this type). Each data series in a stacked area chart uses the top of the previous series as its baseline. Follow the steps below to create stacked spline area series:

1. Use the DxChart.Data property to specify a data source.
2. Add DxChartStackedSplineAreaSeries objects to chart markup. Each series can specify data used via the Data property.
3. Use series ArgumentField and ValueField properties to specify data source fields that supply arguments and values (chart points).
4. Optional. Specify series Filter and SummaryMethod properties to filter and aggregate series values. This demo filters data by region. It also groups arguments by date and calculates aggregate values using the Enumerable.Sum method.

Area-based series support point markers and labels. Use checkboxes to display/hide these elements.
