One way you can do this would be to place Month(Date) on the columns shelf (making it Discrete). Then, create two calculated fields names appropriately by the year, similar to the following:
if year([Order Date])=2012 then Sales end
if year([Order Date])=2013 then Sales end
Then, place both of these calculations on the Measure Values card. Place Measure Values on the rows shelf and Measure Names on the color shelf.
Hope this helps!
