Does this work using the Interactive Graphics Scatterplot? I need do
scatterplots that have a the Mean(Y) line along with an upper and lower
limit but using the formula
2*SD. Right now, i'm just doing the plot and including the Mean(Y) line,
then calculating the upper and lower limits, pasting the graphs into Word
and dragging lines in the approximate locations where they belong.
If i could do this in SPSS, it would sure save me some work.
Thanks
Carol
