Series Points

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

The following image shows Line and bar series points:

Expanded How to Manually Add a Point to a Series

You can manually add points to the series points collection. For this, you need to define a point's argument and its associated values.

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.

The following table lists series that have specific Value parameters:








Candle Stick






Side-by-Side Range Bar

Overlapped Range Bar




Range Area




Range Polar Area




Range Radar Area




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.

Expanded How to Modify Point Representation

You can perform the following actions to configure chart points' appearance and behavior:

  • Aggregate points

    The Data Aggregation allows you to combine several series points into a single point according to the x-axis's measurement unit interval. Specify an aggregating function to define how series points should be processed.

    Non-aggregated data Aggregated data
  • Color points

    It is possible to color points using one of colorizers:

    You can also enable the XYSeries.ColorEach property to draw points using different colors that ChartControlBase.Palette specifies.

  • Show points with labels

    Display series point labels to provide additional information with points, such as a point argument or value.

  • Animate series points

    You can animate series points and configure animation's settings.

  • Customize point marker models

    Modify a series model to change points' appearance. Different series types provide a set of predefined models. You can also create a custom model for a series point.

  • Custom draw series points

    Use the Custom Draw feature to configure series points' appearance.
