As a long-time JMP user (since version 2.0), I have resisted until recently using the new Graph Builder since I was able to easily do what I needed with the now-legacy Overlay Plot functionality. Having recently upgraded to v16, it appears the legacy Overlay Plot function has been altered. Anyway I had been struggling to figure out how to get a simple connect-the-dots set of scatter plots. Your comment solved that problem. I do find it highly annoying that such a simple function is non-obvious, at least as compared to the "legacy" Overlay Plot.
