Access Charting Issue

[Tcurtis]

I am very new to Access and cannot understand how to chart correctly in Access 2010. I have a query that counts the number of parts used and returns the top 10 parts for a given time period. The datasheet works great but when I try to chart out these items, I get results that are not in my query. The chart has a query builder behind it and I checked on it and found that the data there is different than what is in my query. How can this be? This is very baffling to me. Thanks for the help in advance.

Would have to know more about data structure and the queries. If you want to provide db, follow instructions at bottom of my post.
