Scatter Radar Line Chart

  • 3 minutes to read

Short Description

The Scatter Radar Linechart 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.
