My cousin is a grad-school researcher who recently switched to Office 2007 from Office 2003. In 2003, there used to be pattern fills for charts, but, unfortunately, this feature was removed in 2007. Needless to say, the removal of this features was rather bad news for her 🙁 The good news is, there is an add-in that has been written by Andy Pope that fixes this! Let's hope it's what she expected.
Check out Andy's add-in here.
