HowToMeetYou commented on issue #9757: 我猜你只是在setOption中加了curveness: Math.random() URL: https://github.com/apache/incubator-echarts/issues/9757#issuecomment-454298614 links就是setOption中的links，表示指向关系 arr存放所有节点，arr数组其中一个数据 如：arr[2] = {end: (...),endName: (...),obj: (...),rObjDetails: (...),start: (...),startName: (...)} links.push({ 'source': arr[i].start, 'target': arr[i].end, 'sourceName': arr[i].startName, 'targetName': arr[i].endName, 'id': arr[i].obj.id, 'lineStyle': { curveness: Math.random() * 1 + 0.5 }, }) 判断指向关系时要用id(表示唯一)，因为source和target会有重名的情况
