SciChart provides a variety of chart types out of the box, starting from simple iOS line charts and up to complex scientific iOS mesh chart types. This example demonstrates how to create a simple 3D Scatter Chart that is often used in scientific and engineering sectors allowing the visualisation of clustered data and for multi-variant analysis. SciChart iOS Charting Library offers SCIScatterRenderableSeries3D renderable series to create a Simple Scatter Plot in 3D.

The Shape of the scatters is defined with the PointMarkers, this could be a Sphere, Cube, Pyramid or Cylinder shape.

You can learn more about how to create iOS 3D Scatter Plots with SciChart iOS 3D Charting Library in our documentation:
