I have created a cross tab report, image. This is 12 months sales volumes by product line. What I am trying to acheive is when the mouse is hovered over Draught Lager in October, the tool tip will show the previous 5 years information for this product, to compare the same month in previous years. I just dont know how Im going to acheive this. If anyone has any ideas please let me know. Thanks for reading.
