Clever stuff, so A9 to F18 are the Dimensions and the cordinates for the black bars. Col G are the labels for chart. D6 & 7, E6 & 7 generate the green and red bars, with E being a transparent bar in a second series, is that actually required? If you use it for percentages, it looks to go from 0.01 to 7 if you actually want to go from 1 - 100, which is awkward.
