Remarks

If this property is set to True then all points marked as empty are ignored when points are grouped or exported.

If this property is False and a grouping operation occurs (GroupXXX method) then all points marked as empty are treated as zeros.

If this property is False and data is being exported (using the ExportSeriesValues function) then the X-value and Y-value(s) of each empty point are exported as DBNULL objects.

This property is not applied to the Formula method.
