Use the GGRAPH command. Specify all your variables in the GGRAPH part, define them as data using in the GPL section. Specify a point element for each pair and line element for each pair. Use the color or shape function to distinguish the points in each pair. I suspect that there is a simple example of a one pair in the GPL reference that you can start from to develop your syntax.
Note, if you have lots of cases, this chart is likely to look like a busy abstract painting and you might think about just showing the regression lines without the points. In that case, don't use the point element.

I want to make a graph where the same DV is paired with multiple different IVs. I know that I can do this in Graph with syntax like:
GRAPH
/SCATTERPLOT(OVERLAY)=month_year month_year month_year
WITH ed_1000 office_1000 outpatient_1000(PAIR)
/MISSING=LISTWISE.
But I need to be able to create separate regression lines for all three relationships. It’s gotta be done in syntax because the process is to be automated in python.
I know that IGRAPH can produce a regression line in syntax, but can it produce three regression lines with three separate independent variables?
Thanks
