StepLineSeriesView Class

Represents a series view of the Step Line type.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.2.dll

NuGet Package: DevExpress.Charts

#Declaration

public class StepLineSeriesView :
    LineSeriesView,
    ILineSeriesView,
    IStepSeriesView

#Remarks

The StepLineSeriesView class provides the functionality of a series view of the step line type within a chart control.

In addition to the common line view settings inherited from the base LineSeriesView class, the StepLineSeriesView class declares a step line type specific setting which allows you to control the manner in which step lines are drawn within the view (StepLineSeriesView.InvertedStep).

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 step line type please see the Step Line Chart topic.

#Example

The following example demonstrates how to create a ChartControl with a series of the StepLineSeriesView 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 stepLineChart = new ChartControl();

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

    // Add points to it.
    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 the series to the chart.
    stepLineChart.Series.Add(series1);

    // Customize the view-type-specific properties of the series.
    StepLineSeriesView myView = (StepLineSeriesView)series1.View;
    myView.LineMarkerOptions.Kind = MarkerKind.Star;
    myView.LineMarkerOptions.StarPointCount = 5;
    myView.LineStyle.DashStyle = DashStyle.Dash;

    // Access the diagram's options.
    ((XYDiagram)stepLineChart.Diagram).EnableAxisXZooming = true;

    // Hide the legend (if necessary).
    stepLineChart.Legend.Visible = false;

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

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