XYZ Scatter Point charts are created by using an instance of the PointSeries object. Both the UseXValues (inherited from the XYScatterSeries base class) and the UseZValues properties must be set to true. The following figure demonstrates an XYZ scatter point chart.

Notes on Scaling XYZ Scatter Point Charts

Custom X-coordinates (extracted from the XValues data series) are scaled on the specified X-axis (by default the PrimaryX axis), while custom Z-coordinates are scaled on the Depth axis. 

Since both the PrimaryX and Depth axes by default operate in Dimension mode, the user must manually change this scaling mode to one of the value scaling modes (Numeric, DateTime or Logarithmic). The following code will correctly display an XYZ scatter point chart.

' there is one chart created by default
Dim chart As Chart = CType(chartControl1.Charts(0), Chart)
  
poInteger.UseXValue = True
poInteger.UseZValue = True
  
chart.Axis(StandardAxis.PrimaryX).ScaleMode = AxisScaleMode.Numeric
chart.Axis(StandardAxis.Depth).ScaleMode = AxisScaleMode.Numeric

// there is one chart created by default
Chart chart = (Chart)chartControl1.Charts[0];

point.UseXValue = true;
point.UseZValue = true;

chart.Axis(StandardAxis.PrimaryX).ScaleMode = AxisScaleMode.Numeric;
chart.Axis(StandardAxis.Depth).ScaleMode = AxisScaleMode.Numeric;

Please refer to the Axis Scales topic for more information.
