Also, line graphing may or may not be working, last we heard it was in beta stage when we installed it. Unfortunately, Google Maps being unsupported post-May 19th forced our hand waiting to make sure that new feature was stable on Maps. If it does indeed appear to be unsupported on this version, I will email the Maps developers later asking for a timetable.
