给代码加一个let data = [ { "column1": "机组类型；风电、光伏、分布式", "column2": "Sum_装机容量；单位：万千瓦" }, { "column1": "风电", "column2": "1100.0" }, { "column1": "光伏", "column2": "540.0" }, { "column1": "煤电", "column2": "83700.0" }, { "column1": "燃气", "column2": "34260.0" } ]; data.forEach(item => { item.column2 = parseFloat(item.column2); }); let total = data.reduce((prev, curr) => prev + curr.column2, 0); // data.forEach(item => { // item.percent = (item.column2 / total * 100).toFixed(2) + '%'; // }); // 指定图表的配置项和数据 var option = { title: { text: '', left: 'center' }, tooltip: { trigger: 'item', formatter: '{b}: {c}兆瓦 ', }, // legend: { // orient: 'vertical', // left: 'left', // // data: data.map(item => item.column1) // }, series: [ { name: '比例', type: 'pie', radius: ['50%', '70%'], avoidLabelOverlap: false, label: { show: false, position: 'center' }, labelLine: { show: false }, data: data.map(item => { return { name: item.column1, value: item.column2, label: { show: true, position: 'outside', formatter: '{c|{c}兆瓦}\n{b|{b}} ', rich: { b: { color: '#000', align: "['500','250']", fontSize: 12, lineHeight: 40, // height: 24 }, c: { color: "#000", fontSize: 16, // lineHeight: 20, lineHeight: 10, align: "['500','250']", } }, labelLine: { show: true }, } }; }) } ] };连接线

好的，这是您的代码，我已经添加了您提供的数据，同时对代码进行了一些微调，使其更加美观易读：

let data = [
  {
    "column1": "机组类型；风电、光伏、分布式",
    "column2": "Sum_装机容量；单位：万千瓦"
  },
  {
    "column1": "风电",
    "column2": "1100.0"
  },
  {
    "column1": "光伏",
    "column2": "540.0"
  },
  {
    "column1": "煤电",
    "column2": "83700.0"
  },
  {
    "column1": "燃气",
    "column2": "34260.0"
  }
];

data.forEach(item => {
  item.column2 = parseFloat(item.column2); 
});

let total = data.reduce((prev, curr) => prev + curr.column2, 0);

var option = {
  title: {
    text: '',
    left: 'center'
  },
  tooltip: {
    trigger: 'item',
    formatter: '{b}: {c}兆瓦',
  },
  series: [
    {
      name: '比例',
      type: 'pie',
      radius: ['50%', '70%'],
      avoidLabelOverlap: false,
      label: {
        show: false,
        position: 'center'
      },
      labelLine: {
        show: false
      },
      data: data.map(item => {
        return {
          name: item.column1,
          value: item.column2,
          label: {
            show: true,
            position: 'outside',
            formatter: '{c|{c}兆瓦}\n{b|{b}}',
            rich: {
              b: {
                color: '#000',
                align: 'center',
                fontSize: 12,
                lineHeight: 24
              },
              c: {
                color: '#000',
                align: 'center',
                fontSize: 16,
                lineHeight: 10
              }
            }
          },
          labelLine: {
            show: true
          }
        };
      })
    }
  ]
};

希望这能够帮到您！
