Scott -
This sounds like a listwise deletion vs. pairwise deletion issue. Check the
n for each graph. If the n changes from situation to situation (2 graphs, 3
graphs, etc...) then you've spotted the problem.

Subject: Graphs something different than descriptives
Why would SPSS graphs of a mean show different results than the
descriptives table? When I graph any 2 of my variables side by side, it
shows the same values as in the table. When I graph 3 or more at the same
time, the values change. Nothing is different except the number of other
variables I am graphing it with. Why would it graph correctly in one
instance and not the other? Nothing in the data is changing. Could it be
calculating the means based upon something I am not considering?
Thanks!
