Execution: Runs during GraphPack series post-processing for each generated TBoxSeries, before its sample values are sorted and its statistics are recalculated. The same formula contract is used by BoxPlot and Quick BoxPlot.
Arguments: No event-specific arguments are declared.
Result: Return a numeric position. A successful result is assigned directly to TBoxSeries.Position. NeedResult=True; do not return Null or text.
Error handling: A calculation error raises an exception and stops GraphPack post-processing.
Availability: Desktop and the server-side GraphPack refresh used by web.
Example: Position the BoxPlot series at 2.5.
