Using this mode you can emulate Z axis in 3D chart.
- Only lines and points series.
- All points in series have same Z value, so you can't draw line between different Z locations.
- No labels on Z axis. You can try to workaround with empty points + labels, or anchoring TextAnotations to empty points.
See ChartArea3D ZDepthRealCalc sample for details.
