Demonstrates how to use ColumnRenderableSeries3D type and create a 3D Sparse Column Chart in SciChart Android. The ColumnRenderableSeries3D accepts either XyzDataSeries3D for sparse points, or UniformGridDataSeries3D for an NxM array of points.

Column charts are typically used when you need to compare a single category of data between sub-items.

The SciChart Android API for column series allows to have a different number of column rows. It lets manipulating the column size, as well as supports different columns’ shapes out of the box: SpherePointMarker3D, CubePointMarker3D, PyramidPointMarker3D, CylinderPointMarker3D
