如上图,自动布局下,我的连线应该是 {from 1 to 1, {from 1 to 2 }, {from 2 to 2}

First, if you don’t use Orthogonal or AvoidsNodes Link.routing, the paths should be quite clear – much as your red arrows are.

Second, you could increase the value of Link.corner to make turns clearer.

Third, you could vary each node’s fromEndSegmentLength and toEndSegmentLength, which can help change where the routes turn. Or you could change where the nodes are along the x-axis to get a similar effect.

I think the first choice, not using orthogonal routing, is the best.
