StackedSplineAreaSeriesView Class

Represents a series view of the Stacked Spline Area type.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v20.1.dll

Declaration

public class StackedSplineAreaSeriesView :
    StackedAreaSeriesView,
    ISplineSeriesView,
    ISplineView,
    IStackedSplineView,
    IStackedView
Public Class StackedSplineAreaSeriesView
    Inherits StackedAreaSeriesView
    Implements ISplineSeriesView,
               ISplineView,
               IStackedSplineView,
               IStackedView

Remarks

The StackedSplineAreaSeriesView class provides the functionality of a series view of the Stacked Spline Area type within a chart control.

In addition to the common view settings inherited from the base StackedAreaSeriesView class, the StackedSplineAreaSeriesView class declares the spline type specific settings, which allow you to define the style of the spline curve (StackedSplineAreaSeriesView.LineTensionPercent).

Note that a particular view type can be defined for a series via its SeriesBase.View property.

For more information on series views of the Stacked Spline Area type, refer to the Stacked Spline Area Chart topic.

Examples

The following example demonstrates how to create a ChartControl with a series of the StackedSplineAreaSeriesView type, set its general properties, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.

using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl stackedSplineAreaChart = new ChartControl();

    // Create two stacked spline area series.
    Series series1 = new Series("Series 1", ViewType.StackedSplineArea);
    Series series2 = new Series("Series 2", ViewType.StackedSplineArea);

    // Add points to them.
    series1.Points.Add(new SeriesPoint("A", 80));
    series1.Points.Add(new SeriesPoint("B", 20));
    series1.Points.Add(new SeriesPoint("C", 50));
    series1.Points.Add(new SeriesPoint("D", 30));

    series2.Points.Add(new SeriesPoint("A", 40));
    series2.Points.Add(new SeriesPoint("B", 60));
    series2.Points.Add(new SeriesPoint("C", 20));
    series2.Points.Add(new SeriesPoint("D", 80));

    // Add both series to the chart.
    stackedSplineAreaChart.Series.AddRange(new Series[] { series1, series2 });

    // Adjust the view-type-specific options of the series.
    ((StackedSplineAreaSeriesView)series1.View).LineTensionPercent = 10;
    ((StackedSplineAreaSeriesView)series2.View).LineTensionPercent = 70;

    // Access the diagram's options.
    ((XYDiagram)stackedSplineAreaChart.Diagram).EnableAxisXZooming = true;

    // Hide the legend (if necessary).
    stackedSplineAreaChart.Legend.Visible = false;

    // Add a title to the chart (if necessary).
    stackedSplineAreaChart.Titles.Add(new ChartTitle());
    stackedSplineAreaChart.Titles[0].Text = "A Stacked Spline Area Chart";
    stackedSplineAreaChart.Titles[0].WordWrap = true;

    // Add the chart to the form.
    stackedSplineAreaChart.Dock = DockStyle.Fill;
    this.Controls.Add(stackedSplineAreaChart);
}
