3 minutes to read

Short Description

The Scatter Radar Line chart is represented by the ScatterRadarLineSeriesView object, which belongs to Radar Series Views. The series points are displayed in the same order they were added to the collection, without aggregation by the argument. This feature is the main difference between this and other series types, that sort and group points by arguments.

For example, the following image demonstrates a Scatter Radar Line Chart, representing a graph for the Polar Rose function.

Chart Type Characteristics

The table below lists the main characteristics of this chart type.

Feature	Value
Series View type	ScatterRadarLineSeriesView
Diagram type	2D-RadarDiagram
Number of arguments per series point	1
Number of values per series point	1

Note

For information on which chart types can be combined with the Scatter Radar Line Chart , refer to the Series Views Compatibility document.
This series view type is displayed correctly only if scale types of axes are numeric continuous.

Example

The following example demonstrates how to create a Scatter Radar Line Chart chart at runtime.

Note that this series view type is associated with the RadarDiagram type, and you should cast your diagram object to this type in order to access its specific options.
