@David Kosakowski
Is it possible to create a histogram where the QTY remains the same for each week instead of weekly progress?
Total Barrier Length = 150m
Week 1 - 150m Barriers required to hire
Week 2 - 150m Barriers required to hire
Week 3 - 150m Barriers required to hire
So over a period of 3 weeks, we require 150m of barrier hire
What I would like to do is to have multiple tasks calculated by length or qty, showing the peak histogram for traffic management barrier/cones requirements for the project

Also it would good if we could add cost
Hire Option
Week 1 - 150m @ $20/m = $300
Week 2 - 150m @ $20/m = $300
Week 3 - 150m @ $20/m = $300
Total Cost = $900
