To convert from pixel coordinates to data coordinates, call the CoordToDataCoord method. For example, the following converts the pixel coordinates (225, 92) to their equivalent data coordinates:

To write code in Visual Basic

Dim DataX As Double
Dim DataY As Double
Dim DataZ As Double

C1Chart3D1.ChartGroups(0).ChartData._CoordToDataCoord(225, 92, DataX, DataY, DataZ)
' DataX, DataY and DataZ now contain the data coordinate value.

To write code in C#

double DataX=0, DataY=0, DataZ=0;

C1Chart3D1.ChartGroups[0].ChartData.CoordToDataCoord(225, 92, ref DataX, ref DataY, ref DataZ);
// DataX, DataY and DataZ now contain the data coordinate value.

CoordToDataCoord returns False if there is no data corresponding these pixel coordinates.
