In SciChart Android 3D Column Charts are provided by the ColumnRenderableSeries3D type. This example shows how to use this type and UniformGridDataSeries3D for an NxM array of points to create an Android Uniform Column Chart in 3D.

You can manipulate the number of rows of columns, columns shapes with several point markers provided out of the box as well as set the column size and color.

Please read more about The Column 3D Chart Type in SciChart Android 3D Documentation.
