javascript - 桑基图节点从低到高排序

Question

const dataSeries = [{
        "name": "Containerburg"
      },
      {
        "name": "HTCont1"
      },
      {
        "name": "Kranstrom"
      },
      {
        "name": "Wago3"
      },
      {
        "name": "Wago5"
      },
      {
        "name": "Wago2"
      },
      {
        "name": "Heinrich Campus "
      },
      {
        "name": "SubCont1"
      },
      {
        "name": "Heinrich Campus"
      }
    ];

    const seriesLinks = [{
        "source": "Containerburg",
        "target": "HTCont1",
        "value": 20.874000000000024
      },
      {
        "source": "Kranstrom",
        "target": "Wago3",
        "value": 44.253999999999905
      },
      {
        "source": "Containerburg",
        "target": "Wago5",
        "value": 126.2489999999998
      },
      {
        "source": "Kranstrom",
        "target": "Wago2",
        "value": 151.63200000000006
      },
      {
        "source": "Heinrich Campus ",
        "target": "Kranstrom",
        "value": 195.88599999999997
      },
      {
        "source": "Containerburg",
        "target": "SubCont1",
        "value": 745.3199999999997
      },
      {
        "source": "Heinrich Campus",
        "target": "Containerburg",
        "value": 892.4429999999995
      }
    ];

option = {
  series: [
    {
      type: "sankey",
      data: dataSeries,
      links: seriesLinks,
    },
  ],
};

Apache ECharts 自动将其从高值排序到低值（SubCont1 < HTCont1），但我想颠倒排序，使 HTCont1 在顶部，SubCont1 在底部。

这是一个工作示例，可以粘贴到https://echarts.apache.org/examples/en/editor.html或者可以在此处查看http://jsfiddle.net/y7emL1np/

Answer 1

您可以使用layoutIterations参数来实现这一点。将其设置为 0（零）会禁用所有基于权重/值的布局调整。 http://jsfiddle.net/yj5u9htb/

    var option = {
      series: [{
        type: "sankey",
        data: dataSeries,
        links: seriesLinks,
        layoutIterations: 0
      }]
    };

    myChart.setOption(option);

Answer 2

series: [{
  // ...
  layoutIterations: 0,
  // ...
}]

您禁用了布局优化，现在您需要自己更改顺序:)

const seriesLinks = [{
  // ...
}].reverse() // <--- this

看一个固定的例子：
