The forecast functionality in SiteCatalyst is a bit inconsistent. Often it only works until you update your report to a custom date range, then if you go back to a Pre-Set date range the forecast will no longer appear. It would be great to have a Forecast Toggle option for both the graphs AND reports, so you can see visually and in the data how you're trending per day, month, year, etc. In the report table, this could show up above the results table with a textual representation of the forecast.
