PointSeriesView Class
Represents a series view of the Point type.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v24.2.dll
Declaration
Remarks
The PointSeriesView class provides the functionality of a series view of the point type within a chart control. At the same time, the PointSeriesView class serves as a base for the LineSeriesView and StepLineSeriesView classes and so provides the common functionality for point and line series views.
In addition to the common view settings inherited from the base SeriesViewBase class, the PointSeriesView class declares specific point type settings which allow you to define the settings of point markers (PointSeriesView.PointMarkerOptions).
Note that a particular view type can be defined for a series using its SeriesBase.View property.
For more information, refer to Point Chart.
Example
The following example demonstrates how to create a ChartControl with a series of the PointSeriesView 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 pointChart = new ChartControl();
// Create a point series.
Series series1 = new Series("Series 1", ViewType.Point);
// Set the numerical argument scale type for the series,
// as it is qualitative, by default.
series1.ArgumentScaleType = ScaleType.Numerical;
// Add points to it.
series1.Points.Add(new SeriesPoint(1, 10));
series1.Points.Add(new SeriesPoint(2, 22));
series1.Points.Add(new SeriesPoint(3, 14));
series1.Points.Add(new SeriesPoint(4, 27));
series1.Points.Add(new SeriesPoint(5, 15));
series1.Points.Add(new SeriesPoint(6, 28));
series1.Points.Add(new SeriesPoint(7, 15));
series1.Points.Add(new SeriesPoint(8, 33));
// Add the series to the chart.
pointChart.Series.Add(series1);
// Access the view-type-specific options of the series.
PointSeriesView myView1 = (PointSeriesView)series1.View;
myView1.PointMarkerOptions.Kind = MarkerKind.Star;
myView1.PointMarkerOptions.StarPointCount = 5;
myView1.PointMarkerOptions.Size = 20;
// Access the type-specific options of the diagram.
((XYDiagram)pointChart.Diagram).EnableAxisXZooming = true;
// Hide the legend (if necessary).
pointChart.Legend.Visible = false;
// Add a title to the chart (if necessary).
pointChart.Titles.Add(new ChartTitle());
pointChart.Titles[0].Text = "A Point Chart";
// Add the chart to the form.
pointChart.Dock = DockStyle.Fill;
this.Controls.Add(pointChart);
