For charting purposes, build a table that has the products in rows, and the dates in the column headers. Then each data series will be a single, simple range within a row.
That way you can easily define the time frame that you want to show in the chart.
If you also want a table that illustrates to the reader the difference between last year and the current year, by all means, build this table as a report, but do not try to use that report structure as the source data for your chart.
Keep it simple.
You may need to duplicate some data, but you will save a lot of headache.
cheers, teylyn
