Handling Missing Data
If one coordinate for a data point is set to a special value known as the hole value, the chart treats the data point as a missing value, and does not display it on the chart. This hole value is specified by the Hole property of the Chart3DDataSet object.
For example, the following code treats the point in the third row and first column as a missing value:
To write code in Visual Basic
Dim gridset As Chart3DDataSetGrid
gridset = C1Chart3D1.ChartGroups(0).ChartData.SetGrid
With gridset
.Hole = 999.1
.Item(0, 2) = 999.1
End With
To write code in C#
Chart3DDataSetGrid gridset = C1Chart3D1.ChartGroups[0].ChartData.SetGrid;
gridset.Hole = 999.1f;
gridset[0,2] = 999.1f;
