Can you give us some sample data, and even a mock-up of what you are looking for based on the data? How do Open/Closed Pendin Status relate to each other, and are you looking for a Count or Sum of some data?
.... one more question... "Wht's the big picture here..."... I'm confused how a line WAY at the bottom of a stack (5%) is related here? Are you trying to say, 5% of a tech's closed tickets are allowed to be open? If so, I would imaging the stack with Closed and Open tickets, then the line = 105% of the closed total. If the Open (tip) of each Stack goes ABOVE the line, they have too many open tickets compared to the 5% closed???
