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);
