The Ellipsoid 3D Chart Type

In SciChart, Ellipsoid 3D Charts are provided by the combination of the Free Surface 3D Series and SCIEllipsoidDataSeries3D underlying DataSeries.

The location of the SCIEllipsoidDataSeries3D is defined by following properties:

The size of the SCIEllipsoidDataSeries3D is defined by following properties:

Create a Ellipsoid 3D Chart

To create a Ellipsoid 3D Chart, use the following code:
