Comment 28 for bug 121510

I know that the function has been implemented for a few months now, but I find that the manual lacks any reference points for understanding how it works. Is it based on previous years to predict? Is it based on planned income and expenditure? The graph is interesting, but I think it would be easier to read if it were displayed in a window with details of forecasts made.
Are there any plans to at least include details in the software user manual?
