Remarks

Each series represents a set of data points. A series holds its data points within its Series.Points collection, represented by the SeriesPointCollection class. The properties and methods exposed by the SeriesPointCollection class can be used to perform common collection operations such as adding new or deleting existing items. Each item of the collection is represented by a SeriesPoint object. Individual items can be accessed using indexer notation.

Data points are automatically added to a collection of the SeriesPointCollection type when a series is bound to a data source (data binding can be performed using a series’ Series.DataSource property). If a series is not bound to data, the collection of data points can be populated manually, at design time or runtime.

Example

The following example demonstrates how to create a 2D Side-by-Side Bar. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add two series with points to the diagram’s Diagram.Series collection.
