I don't know if it is possible - but if it is not:
Concider to represent the data in a "Grid chart" instead since what you request might be not so easy to understand anyway, at least if you will have many years and more that 3 product groups.
Doing this in a grid chart will make it very visible which product is greatest in which year - you get what you want but in another way.
Se attached doc. I took the same example you sent, but chaged the chart into a grid chart instead.
