This examples shows how to use ImpulseRenderableSeries3D and UniformGridDataSeries3D to create a Uniform Impulse (Stem) 3D Android Chart. 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:
