This example showcases how to create a Simple 3D Polar Chart in Android with SciChart. Polar 3D Charts are rendered by the PolarDataSeries3D type and FreeSurfaceRenderableSeries3D.

The SciChart Android chart library API allows you to define the Polar’s location and size, as well as set different palette modes (Radial, Axial, Polar and Azimuthal).

FreeSurfaceRenderableSeries3D allows you to create all kinds of shapes, including Sphere, Cylinder, Disc and free-form mesh shapes, and overlay heightmap, colormap (palette) and contours, empowering your slick Android applications. Take a look at other examples of shapes in this section: simple cylindroid chart, simple ellipsoid chart, closed mesh chart and a realtime ellipsoid mesh chart example.
