Public ReadOnly Property Points As SeriesPointCollection
| Type | Description |
|---|---|
| SeriesPointCollection |
A SeriesPointCollection object that represents the data point collection of the series.
|
The Points property provides access to a collection of data points that belong to an individual series. The SeriesPointCollection class represents the series point collection and allows you to manage (add, remove, access via indexer notation, etc.) individual series points (instances of the SeriesPoint class) within the collection.
Important
The series Points collection may provide series points that represent data source objects. These points are generated on the first getting of series points. For performance reasons, it is strongly recommended not to request series points when the series is data bound.
The Chart Control does not generate series points until it loads a data source. Use the ChartControl.BoundDataChanged (WebChartControl.BoundDataChanged or ChartControlSettings.BoundDataChanged) event to obtain a collection of generated points.
The series can sort its points that have qualitative arguments before displaying them using the SeriesBase.SeriesPointsSorting) and SeriesBase.SeriesPointsSortingKey properties. Refer to the Sorting Data guide for more information.
The following example demonstrates how to create a ChartControl with two series of the SideBySideBarSeriesView 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.
