    },
    tooltip: {
      trigger: 'item'

    legend: { // 对图形的解释部分
      orient: 'vertical',
      right: 10,
      y: 'center',
      icon: 'circle',
      formatter: (name : any) => {
        let total = 0
        let target
        for (let i = 0; i < dataPost.length; i++) {
          total += dataPost[i].value
          if (dataPost[i].name === name) {
            target = dataPost[i].value
          }
        }
        const arr = [
          '{a|' + name + '}',
          '{b|' + target + '}',
          '{c|' + ((target / total) * 100).toFixed(2) + '%}'
        ]
        return arr.join('  ')
      },
      textStyle: {
        padding: [10, 0, 0, 0],
        rich: {
          a: {
            fontSize: 15,
            width: 135
          },
          b: {
            fontSize: 15,
            width: 50,
          },
          c: {
            fontSize: 15,
            color: '#c1c1c1'
          },
        }

        type: 'pie',
        radius: ['40%', '70%'],
