Example

The following example demonstrates how to create a ChartControl with a series of the LineSeriesView type, 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 lineChart = new ChartControl();

    // Create a line series.
    Series series1 = new Series("Series 1", ViewType.Line);

    // Add points to it.
    series1.Points.Add(new SeriesPoint(1, 2));
    series1.Points.Add(new SeriesPoint(2, 12));
    series1.Points.Add(new SeriesPoint(3, 14));
    series1.Points.Add(new SeriesPoint(4, 17));

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

    // Set the numerical argument scale types for the series,
    // as it is qualitative, by default.
    series1.ArgumentScaleType = ScaleType.Numerical;

    // Access the view-type-specific options of the series.
    ((LineSeriesView)series1.View).MarkerVisibility = DevExpress.Utils.DefaultBoolean.True;
    ((LineSeriesView)series1.View).LineMarkerOptions.Kind = MarkerKind.Triangle;
    ((LineSeriesView)series1.View).LineStyle.DashStyle = DashStyle.Dash;

    // Access the type-specific options of the diagram.
    ((XYDiagram)lineChart.Diagram).EnableAxisXZooming = true;

    // Hide the legend (if necessary).
    lineChart.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;

    // Add a title to the chart (if necessary).
    lineChart.Titles.Add(new ChartTitle());
    lineChart.Titles[0].Text = "A Line Chart";

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