This example demonstrates several features of the Cartesian chart that ensure
better visibility and readability for 3D charts that are frequently rotated.
When the automatic visibility mode of the chart walls is enabled, chart
walls are dynamicaly shown and hidden so that the data is never overlapped by a wall.
The automatic docking axis anchor chooses an appropriate edge of the Cartesian chart box for an axis,
depending on the current projection properties. The axes are displayed on side edges, not in front
of the data or behind the chart.
The light source coordinates can be defined in camera space so that light sources are dynamically
repositioned as you rotate the chart. In this way the scene is always well lit.
