Short Description

The Area Chart is represented by the Area3DSeriesView object, which belongs to Area Series Views. This view displays series as filled areas on a diagram, with each data point displayed as a peak or hollow in the area. This view is useful when you need to show trends for several series on the same diagram, and also show the relationship of the parts to the whole.

An Area chart is shown in the image below.

Chart Type Characteristics

The table below lists the main characteristics of this chart type.

Feature	Value
Series View type	Area3DSeriesView
Diagram type	XYDiagram3D
Number of arguments per series point	1
Number of values per series point	1

Note

For information on which chart types can be combined with the Area Chart, refer to the Combining Different Series Views document.

Example

The following example demonstrates how to create a ChartControl with a series of the Area3DSeriesView 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.

C#

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

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl areaChart3D = new ChartControl();

    // Add an area series to it.
    Series series1 = new Series("Series 1", ViewType.Area3D);

    // Add points to the series.
    series1.Points.Add(new SeriesPoint("A", 10));
    series1.Points.Add(new SeriesPoint("B", 2));
    series1.Points.Add(new SeriesPoint("C", 14));
    series1.Points.Add(new SeriesPoint("D", 7));

    // Add the series to the chart.
    areaChart3D.Series.Add(series1);

    // Customize the view-type-specific properties of the series.
    ((Area3DSeriesView)series1.View).AreaWidth = 5;

    // Access the diagram's options.
    ((XYDiagram3D)areaChart3D.Diagram).ZoomPercent = 110;

    // Add a title to the chart and hide the legend.
    ChartTitle chartTitle1 = new ChartTitle();
    chartTitle1.Text = "3D Area Chart";
    areaChart3D.Titles.Add(chartTitle1);
    areaChart3D.Legend.Visible = false;

    // Add the chart to the form.
    areaChart3D.Dock = DockStyle.Fill;
    this.Controls.Add(areaChart3D);
}

VB.NET

Imports System
Imports System.Windows.Forms
Imports DevExpress.XtraCharts
' ...

Private Sub Form1_Load(ByVal sender As Object, _ 
ByVal e As EventArgs) Handles MyBase.Load
    ' Create a new chart.
    Dim areaChart3D As New ChartControl()

    ' Add an area series to it.
    Dim series1 As New Series("Series 1", ViewType.Area3D)

    ' Add points to the series.
    series1.Points.Add(New SeriesPoint("A", 10))
    series1.Points.Add(New SeriesPoint("B", 2))
    series1.Points.Add(New SeriesPoint("C", 14))
    series1.Points.Add(New SeriesPoint("D", 7))

    ' Add the series to the chart.
    areaChart3D.Series.Add(series1)

    ' Customize the view-type-specific properties of the series.
    CType(series1.View, Area3DSeriesView).AreaWidth = 5

    ' Access the diagram's options.
    CType(areaChart3D.Diagram, XYDiagram3D).ZoomPercent = 110

    ' Add a title to the chart and hide the legend.
    Dim chartTitle1 As New ChartTitle()
    chartTitle1.Text = "3D Area Chart"
    areaChart3D.Titles.Add(chartTitle1)
    areaChart3D.Legend.Visible = False

    ' Add the chart to the form.
    areaChart3D.Dock = DockStyle.Fill
    Me.Controls.Add(areaChart3D)
End Sub
