Which version of office are you using.
With Office 2003, which is the version I use, you can just copy what you want from the excel document into the word document, including diagrams and graphs. So you probably just need to make the graphic in excel and then copy it into word. Some versions of word will allow you to edit the infomation for graphs with a similar editor to excel but from within word.
Here's a link for word 2007 (I think).
