The SeriesPoint class implements the functionality of an individual data point in a series. Each data point is defined by values of the following two types.
The visual representation of data points is specific to the view type of a series.
Data points that belong to the same series are stored within its Series.Points collection, represented by an instance of the SeriesPointCollection class. This collection provides the standard means for manipulating its items such as adding, removing and accessing them. A particular data point is available via the SeriesPointCollection.Item property of the collection, using indexer notation.
The length of an array that contains data values of a point can be obtained via the point’s SeriesPoint.Length property. An individual value of a data point can be accessed via the SeriesPoint.Values property using indexer notation (see the SeriesPoint.Item property).
The sequence in which series points are drawn corresponds to the order they have in the collection. However, data bound series may expose a more sophisticated drawing sequence (especially when complicated data bindings are involved, or events like ChartControl.BoundDataChanged are handled, and when the qualitative scale type is used). In such situations, if it’s required that series points are drawn in a strictly determined sequence, this can be achieved by adding a static series with points arranged in the required way, and setting this series as the first item in the collection.
Series points can be sorted dependent on either their values, or arguments. For details on this, refer to Sorting Data.
For more information, refer to Series Points.
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.
