I was just playing around with it and wanted to make a straight line slope in the opposite direction. Not that I knew that it would be useful. I can move the triangles at the bottom to change the x-position of the spline nodes and then drag the line to do something like what I want, but that changes the splines, or something like that. So I would be changing two things at once. It appears the straight line was programmed in, and that’s the only way to get it.
