I have a graphs two graphs that I have developed where I want to combine `splines=line` and `splines=curved`. I want it to look like this: ![model_fin](https://global.discourse-cdn.com/graphviz/original/1X/e3249f263ebf69d2bbc7e713ee4ff32fd72d6134.jpeg) I have been given great advice on StackOverflow that @steveroush kindly helped with: 1. One that process two graphs and joins them via `gvpack` [here](https://stackoverflow.com/questions/69341993/graphs-with-mixed-splines-or-merge-layers-with-different-splines/69353248?noredirect=1#comment122584483_69353248). This is the output: ![model_n](https://global.discourse-cdn.com/graphviz/original/1X/1ddf5d29b7c2dee276470b69701d2c968a205591.png) 1. And one that takes two passes of the same graph after adding arguments in the `edge` statements, i.e., `edge[keep=1]` which is later post-processed via `gvpr` [here](https://stackoverflow.com/questions/62687030/is-there-a-way-to-have-different-edge-splines-between-nodes-in-the-same-cluster). And this is the output with the splines as `line` then `true`: ![gv_help](https://global.discourse-cdn.com/graphviz/original/1X/dfd70ddf9f14ed914877b7afc684471098109284.png) My preferred option is 2 because I only have to deal with one graph, however the `splines=curved` argument won’t complete it, maybe because there are so many edges to align… I’m not sure. I have posted the syntax for option 2 below, but syntax is essentially the same. I can post both if needed, but don’t want to pollute the post unnecessarily. Can someone please help me get this working? Please let me know if you need any more info regarding my questions. Thanks in advance. * * * ```auto digraph dot { // splines = curved; // splines = spline; // defualt // splines = line; // splines = ortho; // concentrate = true;3.9 // compound = true; // overlap = false;. // graph[fontname = arial, margin = 0, compound = true, pack = true] // graph[fontname = arial, margin = 0, compound = true, pack = true, rank = same] node[fontname = arial, width = 0.0, height = 0.0, fixedsize = true, shape = point, fontsize = 44, style = filled, penwidth = 6, fillcolor = white];

Getting a spline positioned “just so” can be quite challenging, even without the combo spline problems. I’ll fiddle with it and see how close we can get. Two questions: - Is this a one-time graph, or will there be other variations? - If “necessary”, are you willing to consider a different diagramming language? (Since you are already doing the layout yourself) ---

Thanks @steveroush. 1. This is probably a onetime graph, but I could use it as a template in future as it reflect a statistical model that I am likely to use again. That’s why I wanted to get this right programmatically rather than hacking together with a GUI app. 2. Yes, I am open to something else… P.S. I’ve tried running the `gvpack -u` instead of the `-array_` flag with the dual graph run, and it overlays the graphs on top, but they’re out of alignment.
