IGPolarSplineSeries Class Reference
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.
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.property
