Syntax
public class SplineRangeAreaSeries : RangeSeriesBase, IDatapointSelectionDependent, ITooltipDependent, IDataTemplateDependent, IMarkerDependent, IDrawCustomLegendIcon
Remarks

To render a series, create an instance of SplineRangeAreaSeries class, and add it to the Series collection.

EnableTooltip - A tooltip displays information while tapping or mouse hovering above a segment. To display the tooltip on a chart, you need to set the EnableTooltip property as True in SplineRangeAreaSeries class, and also refer TooltipBehavior property.

Data Label - Data labels are used to display values related to a chart segment. To render the data labels, you need to set the ShowDataLabels property as True in SplineRangeAreaSeries class. To customize the chart data labels alignment, placement, and label styles, you need to create an instance of CartesianDataLabelSettings and set to the DataLabelSettings property.

Animation - To animate the series, set True to the EnableAnimation property.

LegendIcon - To customize the legend icon use the LegendIcon property.
