Hi SPSS gurus,
using good ol' v13.
i'm making scatterplots and add a variable (containing 2 levels) as 'color' under 'Legend variables'. i'm also fitting a (linear) regression line per level (thus giving me two regression lines).
now of all the datapoints of level 1 in the graph (30 in total), i'd like to change the shape or color of 3 specific datapoints in the graph, keeping everything else (e.g. the two regression lines) in the graph in place.
is this possible with spss v13?
i hope i've been clear, let me know if you need more info.
many thanks!
