Hi everybody :
i have designed a query about data for every year , and each year has some months , but not every year has integrated data for every month ,it means there have some years only has data less than 12 months.
then i must prepare a chart relevant to this analysis , but i just want every year's overall result data to draw chart ?
how can i gain the overall result about every year ?
who can give some tips ?
tks very much !
