The events OnDataRendered and OnBeforeRenderData provide a hook for adding user defined graphics to the 3D data display. The event OnBeforeRenderData occurs before the data and any axes are drawn. The variable parameter Canvas provides access to the canvas of the data area. Please note that the state of the canvas (e.g. the color of its pen, or the fill mode of the brush) is undefined.
