the query builder become a crosstab query.(below are the query SQL ).
But why my chart cannot displayed the data correctly.My chart display
the data in separate chart ( one chart one dot ).Please help what is wrong.
Or I did a wrong step?

TRANSFORM Sum([Yearly DC Performance tbl Query].[NG Rate]) AS [SumOfNG Rate]
SELECT [Yearly DC Performance tbl Query].Month
FROM [Yearly DC Performance tbl Query]
GROUP BY Month([Month]), [Yearly DC Performance tbl Query].Month
ORDER BY Month([Month]), Year([Month])
