+## ZDepthRealCalc 3DStyle mode.
+
+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/ChartSamples/ChartFeatures/ChartArea/ChartArea3D%20ZDepthRealCalc) sample for details.
