The letter is the person name, the number is the percentage of full time resource, 0.9 = part time.
I would like a bar chart, with total resource count (sum of the numbers for that period) on Y and the Periods on X.
Any idea how to achieve this (one issue i have already hit is the ordering puts P10,P11,P12 out of order, as it treats them as sorting by number after letter, so rather than P9,P10,P11,P12, you get something more like P1,P10,P11,P12,P2)
