vue.js - d3-sankey 链接未在拖动事件上更新

转载作者：行者123 更新时间：2023-12-04 10:38:42

问题 1:我无法在拖动事件上更新 d3-sankey 链接。我正在尝试复制与此类似的 d3 垂直和水平拖动事件:https://bl.ocks.org/d3noob/5028304
当使用拖动事件时，它会更新节点，并且链接不会随之更新。
我也研究过这个 https://observablehq.com/@geekplux/dragable-d3-sankey-diagram我还有其他问题。
我无法在 jsfiddle 中复制代码，所以我在这里共享 JS 代码。

const d3 : any = require('d3');
const sankey : any = require('d3-sankey');

    const width = 960;
    const height = 500;

    const svg = d3.select('#chart')
              .append('svg')
              .attr('viewBox', [0, 0, width, height]);

    const formatNumber = d3.format(',.0f');
    const format = function (d: any) { return `${formatNumber(d)}TWh`; };
    const color = d3.scaleOrdinal(d3.schemeCategory10);

    const path = d3.sankeyLinkHorizontal();

    const sankeyGraph = d3.sankey()
        .nodeWidth(15)
        .nodePadding(10)
        .size([width, height]);

    const graph = JSON.parse(JSON.stringify({
      nodes: mainData.data.nodes.filter((val:any) => {
        return val.name !== '';
      })
      .map((d : any, i : any) => {
        return Object.assign({}, d, { nodeId : i });
      }),
      links: mainData.data.links.filter((val:any) => {
        return (val.source !== '') || (val.target !== '') || (val.value !== '');
      })
      .map((d : any, i : any) => {
        return Object.assign({}, d, { linkId : i });
      }),
    }));

    sankeyGraph(graph);
    let link = svg.append('g')
        .attr('class', 'links')
        .attr('fill', 'none')
        .attr('stroke', '#000')
        .attr('stroke-opacity', 0.2)
        .selectAll('path');

    let node = svg.append('g')
        .attr('class', 'nodes')
        .attr('font-size', 10)
        .selectAll('g');

    link = link
        .data(graph.links)
        .enter()
        .append('path')
        .attr('d', path) // d3.sankeyLinkHorizontal()
        .attr('stroke-width', (d: any) => { return Math.max(1, d.width); });
        // .on('mouseover', handleMouseOver)
        // .on('mouseout', handleMouseOut);

    link.append('title')
        .text((d: any) => {
          return `${d.source.name} → ${d.target.name} -> ${format(d.value)}`;
        });

    node = node
        .data(graph.nodes)
        .enter()
        .append('g');

    node.append('rect')
        .attr('x', (d: any) => { return d.x0; })
        .attr('y', (d: any) => { return d.y0; })
        .attr('height', (d: any) => { return d.y1 - d.y0; })
        .attr('width', (d: any) => { return d.x1 - d.x0; })
        .attr('fill', (d: any) => { return color(d.name.replace(/ .*/, '')); })
        .attr('stroke', '#000')
        .call(d3.drag()
            .subject((d:any) => d)
            // .on('start', () => d3.event.currenTarget.appendChild(d3.event.currenTarget))
            .on('drag', dragmove));

    function dragmove(d:any, i: number, n: any) { // tslint:disable-line
      console.log(d3.event, d3);
      // console.log('drag', d3.event.sourceEvent.target, d3.event, d3.sankey);
      // const m = d3.select(n[i])
      // .node()
      // .getCTM();
      const x = d3.event.x - d3.event.dx;
      const y = d3.event.y - d3.event.dy;
      // console.log(m, x, y);

      d3.select(n[i])
      .attr('x', x)
      .attr('y', y);
// *********the issue is here********
      d3.sankey(graph)
      .update(graph);
      // d3.sankey()
      // .relayout(graph);
      link.attr('d', path); // d3.sankeyLinkHorizontal() 

    }
    node.append('text')
        .attr('x', (d: any) => { return d.x0 - 6; })
        .attr('y', (d: any) => { return (d.y1 + d.y0) / 2; })
        .attr('dy', '0.35em')
        .attr('text-anchor', 'end')
        .text((d: any) => { return d.name; })
        .filter((d: any) => { return d.x0 < width / 2; })
        .attr('x', (d: any) => { return d.x1 + 6; })
        .attr('text-anchor', 'start');

    node.append('title')
        .text((d: any) => {
          return `${d.name} => ${format(d.value)}`;
        });

第 2 期:有时这个事件不能在 Vue-D3 中使用。所以我在拖动开始事件代码时遇到了麻烦。请提出一个替代方案。

this.parentNode.appendChild(this);

第 3 期:有人用 d3-V5 为 sankey 复制了以下内容吗？我需要每个悬停节点前后的流/链接。

最佳答案

这对我有用。

      var node = svg.append('g')
        .selectAll('.node')
        .data(sankeydata.nodes)
        .enter()
        .append('g')
        .attr('class', 'node')
        .attr('transform', d => `translate(${d.x0},${d.y0})`)
        .call(d3.drag()
          .subject(d => d)
          .on('start', function () { this.parentNode.appendChild(this); })
          .on('drag', dragmove))

      function dragmove(d) {
        var rectY = d3.select(this).select("rect").attr("y");
        var rectX = d3.select(this).select("rect").attr("X");
        d.y0 = d.y0 + d3.event.dy;
        d.x1 = d.x1 + d3.event.dx;
        d.x0 = d.x0 + d3.event.dx;
        var yTranslate = d.y0 - rectY;
        var xTranslate = d.x0 - rectX;
        d3.select(this).attr('transform', "translate(" + (xTranslate) + "," + (yTranslate) + ")");
        sankey.update(graph);
        link.attr('d', sankeyLinkHorizontal());
      }
