IGPolarSplineSeries Class Reference

Inherits from IGPolarBase : IGMarkerSeries : IGSeries : NSObject
Declared in Series.h


IGPolarSplineSeries is rendered using a collection of curved lines connecting data points. The IGPolarSplineSeries uses the same concepts of data plotting as the IGScatterSeries but wraps data points around a circle rather than stretching them along a horizontal line. Like with other series types, multiple IGPolarSplineSeries can be plotted in the same chart view and they can be overlaid on top of each other to show differences and similarities between data sets.

IGPolarSplineSeries uses IGNumericAngleAxis and IGNumericRadiusAxis. Markers are placed at the locations of data points. IGPolarSeriesDataSourceHelper can be used as the data source for this series.


A value that determines the curvature of the spline. Smaller values will cause the spline to be more shallow, whle larger values will make the spline more curved.
