LineSeriesView Class

Represents a series view of the Line type.

Namespace:DevExpress.XtraCharts
Assembly:DevExpress.XtraCharts.v19.2.dll

Syntax

Remarks

The LineSeriesView class provides the functionality of a series view of the line type within a chart control. At the same time, the LineSeriesView class serves as a base for the StepLineSeriesView class.

In addition to the common view settings inherited from the base PointSeriesView class, the LineSeriesView class declares the line type specific settings which allow you to define the style of lines (LineStyle) and the settings of line markers (LineMarkerOptions).

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 bar type please see the Line Chart topic.

Example

The following example demonstrates how to create a DevExpress.XtraCharts.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);
}
