Gets or sets the line tension to be used when drawing splines of the SplineAreaFullStackedSeries2D.
Namespace : DevExpress.Xpf.Charts
Assembly : DevExpress.Xpf.Charts.v25.2.dll
NuGet Package : DevExpress.Wpf.Charts
public double LineTension { get; set; }
Public Property LineTension As Double
| Type | Description |
|---|---|
| Double |
A double value specifying the line tension.
|
Use the LineTension property to specify the “smoothness” of a spline curve. Note that if the LineTension property is set to 0 , the SplineAreaFullStackedSeries2D is drawn in the same way as the AreaFullStackedSeries2D.
The following example demonstrates how to create a 2D Full-Stacked Spline Area chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add four SplineAreaFullStackedSeries2D objects with points to the diagram’s Diagram.Series collection.
Also, this example shows how to display series labels on a diagram, customize the label pattern and add a legend (showing series names) to a chart.
