The LineStyle property provides access to the style settings of lines displayed by a series of the line type. These settings allow you to customize the line width and line dash style.

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.

namespace Series_LineChart {
    public partial class Form1 : Form {

        }

        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));

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

            // Set the numerical argument scale types for the series,
