Is it ok to respond to myself here? in case anyone was interested in this, we did find that going to the Cost reports and looking for the Earned Value report in there (this is new in Project 2013), we got wonderful graphs that do match what we see in the tables. However, the Visual Report, “Earned Value over Time” is generating an odd story by factoring in parts of the non-labour costs (actual costs), but not others (eg planned cost).
