Graph controls
Overlap specifies how much 2D bar and column data markers in different series in a graph overlap. The number you specify is a percentage of the width of the data marker. This property is not applicable to all graph types.
To set overlap for bar or column graphs:
Select the desired 2D graph type from the GraphType list on the General page of the control’s Properties view.
Use the OverlapPercent slide control to select the desired percentage of overlap.
The OverlapPercent property takes an integer value. The following line sets the overlap to 10%:
gr_1.OverlapPercent = 10
