Marker

A Marker object that contains the specific marker settings.

Remarks

The LineMarkerOptions property provides access to the settings which define how the data point markers are displayed within a series of the line or step line type.

Note that the settings available via the LineMarkerOptions property can affect the appearance of any related elements (such as series labels and connection lines between markers and labels) if these elements are not customized independently (for instance, via the SeriesBase.Label property).

Examples

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.

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);
}
