I do not recall the particular scatter plot you mention. But see if this gets you what you are looking for.

do a three way scatterplot.
Edit it in the output file.
try a linear fit.
rotate it back and forth to different perspectives.

redo the scatterplot.
Edit it in the output file.
try a loess fit.
rotate it back and forth to different perspectives.

I have 3 continuous variables: the dependent, independent and the moderator.  Baron and Kenny (1986, pp 1175) presented a scatter plot of the moderator variable (Horizontal axis) against the "effect/slope of the independent on the dependent" (Vertical axis).  I wonder if I can do the same for my data (n=100) using SPSS?  I want to visually examine if there is a linear or nonlinear relationship between the moderator and the effect/slope of the independent on the dependent. Your help is very much appreciated.  Thank you.
