Robo0502, only just had time to look into this and it's proved to be quite tricky because there aren't any support materials for charts in Access, versions 2007 and above. In fact there's very little information on programming Access charts, Intellisense doesn't work in the versions listed above, the OWC11.dll (the library for older charts) isn't supported and there isn't a newer version.
But I found a way around it so see attached.
