I'd like to generate a report that plots the revenue against time for a project, or group of projects. I'd like the revenue to be cumulative, i.e. starts at 0, and then increases to the projects total revenue.
For tasks that are complete, it should use the Actual Revenue, and for uncompleted tasks it should use the Expected Revenue.
I've tried a report that plots the Due Date and Revenue of a Project sub-items, but this doesn't plot the cumulative revenue.
Could you give me some guidance on how to achieve this? It sounds like a pretty standard thing to want to do.
