Perhaps this has to be done in GPL but I want to avoid that if possible. Is it possible outside of GPL? So here’s the background.

I can deal with that by controlling the number of persons per graph, therefore multiple graphs per relationship.

The regression variable plots from the dropdown don’t respect the ‘by’ element and I don’t know how to specify
multiple lines per chart. Chartbuilder seems like it might work, I don’t see how either the ‘by’ element or the ‘for’ element is specified or controlled. All that said, I rarely use any graphing, from legacy dialogs (GGRAPH?) to GPL, so I really don’t know
anything. Can someone help? If something is not clear, I’ll certainly do my best to explain better.

Sorry I can't totally grasp what you want. Can you post a snippet of data and
maybe a hand drawn sketch of what you want? I'm guessing you will want to look up the "split()" modifier for GPL elements.

Gene,
How about paneling by the number of relationships? Something like (untested):
GRAPH
/LINE MEAN(Stability) BY Sequence /PANEL COLVAR=Number_of_Relationships COLOP=CROSS.
This doesn't have multiple lines on the same graph, but the paneling provides a side by side visual comparison without a potential jumble or the need to play with line types.

what follows on the real dataset. I want to thank the folks that responded and tried their best to help me. The clear feedback I got was that my explanation—clear to me, of course—was not clear to anybody else. What follows is an example dataset, a couple
of Graph command things I tried last week and the solution I came up that produces what I wanted. Thanks, Gene Maguin

I've tried your syntax and I'm not getting Stability.1, Stability.2, and Stability.3. Instead I'm getting a variable Stability. Is there a bug in my software or does the syntax need tweaking? Thanks.

Andy,
Thank you for your suggestions. I had thought of jitter but not in the way you did it. I kind of think there is a jitter function in gpl but I wanted to stay out of gpl. I like the idea of personspecific plots because they do give better shape visualization and I'll try those out. You mentioned splines and they might be helpful/useful; however, are they implemented in spss and accessible for data series modeling? I haven't ever seen them but I've never wanted to use them.

For person specific plots you would just replace the ELEMENT line in my
suggested plots with something like: COORD: rect(dim(1,2), wrap()) ELEMENT: line(position(relatseq*stabJitt*person), missing.wings(), size(size."1")) I'm not sure offhand if you can jitter entire lines in inline GPL, but yes it is easier often to do it to the data directly. I don't understand your spline question. The splines in the graphs assume no error, it is just a particular formula to interpolate the line. Are you perhaps asking about spline basis functions to model the trajectories over time  like in https://andrewpwheeler.wordpress.com/2013/06/06/restrictedcubicsplinesinspss/? Making those basis functions for individuals is sometimes hard, because if you don't have the same measure points you can sometimes wind up with basis variables that are not identified (depending on the modelling strategy, fixed effects especially).
