Correct, thanks for the clarification.

I still do not understand one part at the http://msdn.microsoft.com/en-us/library/ms980211.aspx page. They have a section in Formatting the Data about how they calculate the XAxis, YAxis and ZAxis. Then, a few lines below, the come up with a different formula. I am not sure which one I should take. Even by having tried them both, I end up with two different results in my query, and both results are not good.
