In this example you can see how we provide SCIImpulseRenderableSeries3D and SCIUniformGridDataSeries3D to create a Uniform Impulse iOS 3D Plot.

A stem chart is visualised as small stems pointing up or down with different kinds of markers at the top, that could be spheres, cubes or else. These shapes are defined by PointMarker property and has the following shapes out of the box:

• SpherePointMarker3D;
• CubePointMarker3D;
• PyramidPointMarker3D;
• CylinderPointMarker3D.
