SciChart Android 3D support selection of a data point, demonstrated at this Scatter Point 3D Chart Selection example.

Tap on a scatter point to select one. You may select several points.
How to use the example! Tap on an already selected point or do a long press on the free chart space to deselect.

The selection of points in SciChart Android 3D is provided by VertexSelectionModifier3D.

Please read on a documentation article about Vertex Selection Modifier in SciChart Android 3D Charts.
