Determining the Closest Data Point
To determine the closest data point to a set of pixel coordinates, call CoordToDataIndex:
To write code in Visual Basic
Dim Row, Column As Integer
C1Chart3D1.ChartGroups(0).ChartData.CoordToDataIndex( 225, 92, Column, Row)
' CoordToDataIndex returns the row and column of the closest data point.
To write code in C#
int Row=0, Column=0;
C1Chart3D1.ChartGroups[0].ChartData.CoordToDataIndex(225, 92, ref Column, ref Row);
// CoordToDataIndex returns the row and column of the closest data point.
