Spline Area

Spline area series display data as colored regions between the argument axis and smooth curves. Follow the steps below to create a spline area series:

1. Use the DxChart.Data property to specify a data source.
2. Add a DxChartSplineAreaSeries object to chart markup.
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.

The DxChart component allows you to add multiple series objects to the component markup. Each series can specify data used via the Data property.

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