Short Description

The Line Chart is represented by the Line3DSeriesView object, which belongs to Line Series Views. This view is useful when you need to show trends for several series on the same diagram, and to compare the values of several series for the same points arguments.

A Line 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	Line3DSeriesView
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 Line Chart , refer to the Series Views Compatibility document.

Example

The following example demonstrates how to create a ChartControl with a series of the Line3DSeriesView 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#
VB.NET

csharp

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

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl LineChart3D = new ChartControl();

    // Add a line series to it.
    Series series1 = new Series("Series 1", ViewType.Line3D);

    // Add points to the series.
    series1.Points.Add(new SeriesPoint("A", 12));
    series1.Points.Add(new SeriesPoint("B", 4));
    series1.Points.Add(new SeriesPoint("C", 17));
    series1.Points.Add(new SeriesPoint("D", 7));
    series1.Points.Add(new SeriesPoint("E", 12));
    series1.Points.Add(new SeriesPoint("F", 4));
    series1.Points.Add(new SeriesPoint("G", 17));
    series1.Points.Add(new SeriesPoint("H", 7));

    // Add both series to the chart.
    LineChart3D.Series.Add(series1);

    // Customize the view-type-specific properties of the series.
    Line3DSeriesView myView = (Line3DSeriesView)series1.View;
    myView.LineWidth = 5;
    myView.LineThickness = 4;

    // Access the diagram's options.
    ((XYDiagram3D)LineChart3D.Diagram).ZoomPercent = 110;
    ((XYDiagram3D)LineChart3D.Diagram).VerticalScrollPercent = 10;

    // Add a title to the chart and hide the legend.
    ChartTitle chartTitle1 = new ChartTitle();
    chartTitle1.Text = "3D Line Chart";
    LineChart3D.Titles.Add(chartTitle1);
    LineChart3D.Legend.Visible = false;

    // Add the chart to the form.
    LineChart3D.Dock = DockStyle.Fill;
    this.Controls.Add(LineChart3D);
}
