syntax for graph with single consistent DV and multiple different IVs

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
