Demonstrates how to use SCIColumnRenderableSeries3D and create a 3D Sparse Column Chart in SciChart iOS. It accepts either SCIXyzDataSeries3D for sparse points, or SCIUniformGridDataSeries3D for an NxM array of points.

The SciChart iOS 3D API is flexible to allow you have different number of column rows, size, and shapes. Column shares are provided by the PointMarkers API and include following out of the box: SpherePointMarker3D, CubePointMarker3D, PyramidPointMarker3D, CylinderPointMarker3D.

Please read more about Column Chart type in iOS and its functionality in our documentation:
