antv-dagre error "Edge not found for id:", the edge and id exist on the graph, and it is no problem to replace it with dagre #6477

我发现是当存在平行边，然后指定layer就会出这个问题，可以用下面的例子 import { Graph } from '@antv/g6';

const data = { nodes: [ { id: '0', layer: 0 }, { id: '01', layer: 0 }, { id: '1', layer: 1 }, { id: '2', layer: 1 }, { id: '-1', layer: -1 }, { id: '-2', layer: -1 } ], edges: [ { source: '0', target: '1' }, { source: '1', target: '0' }, { source: '0', target: '2' }, { source: '-1', target: '0' }, { source: '-2', target: '0' }, ], };

const graph = new Graph({ container: 'container', autoFit: 'view', animation: false, data, layout: { type: 'antv-dagre', rankdir: 'LR', nodeSize: [60, 30], nodesep: 60, ranksep: 40, controlPoints: true, }, node: { type: 'rect', style: { size: [60, 30], radius: 8, labelText: (d) => d.id, labelBackground: true, } }, edge: { type: 'polyline', }, behaviors: ['drag-element', 'drag-canvas', 'zoom-canvas'], });

graph.render();

window.addPanel((gui) => { const config = { layout: 'default' }; const layouts = { default: { type: 'antv-dagre', nodesep: 100, ranksep: 70, controlPoints: true }, LR: { type: 'antv-dagre', rankdir: 'LR', align: 'DL', nodesep: 50, ranksep: 70, controlPoints: true }, 'LR&UL': { type: 'antv-dagre', rankdir: 'LR', align: 'UL', controlPoints: true, nodesep: 50, ranksep: 70 }, };

gui.add(config, 'layout', Object.keys(layouts)).onChange(async (layout) => { graph.setLayout(layouts[layout]); await graph.layout(); graph.fitCenter(); }); });
