A series point is a visual element representing an individual data point. Its appearance depends on the series type.

Add a Point to a Series

You can define a point’s argument and its associated values to add points to the series points collection.

XAML

xaml

<dxc:LineSeries2D DisplayName="Line Series">
    <dxc:SeriesPoint Argument="A"
                     Value="5"/>
    <!-- Other series points. -->
</dxc:LineSeries2D>

The following table contains classes and properties that allow you to populate the Series.Points collection manually:

Class or Property	Description
Series.Points	The series points’ collection. This is a content property. You can declare points in XAML directly after a series declaration without wrapping them in opening and closing Series.Points tags.
SeriesPoint	The series point.
SeriesPoint.Argument	The point’s argument.
SeriesPoint.Value	The point’s value.

Note that a series point in a particular series type may require unique parameters, for instance, a Line series point requires an Argument and Value while a Bubble series point also requires a Weight parameter.

XAML

xaml

<dxc:BubbleSeries2D DisplayName="Planet Mass">
    <dxc:SeriesPoint Argument="Mercury"
                     Value="58" 
                     dxc:BubbleSeries2D.Weight="0.06"/>
    <!-- Other series points. -->
</dxc:BubbleSeries2D>

The following table lists series that have specific Value parameters:

The Chart control displays points with undefined Value parameter as breaks in Line or Area series, and missing points or bars in other series types.

You can automatically populate chart with data by binding a Chart control to a data source. Refer to the Bind a Series to a Data Source document for more details.
