自定义标签和强调标签重叠

Question

我尝试让饼图显示 'customized label'，当鼠标触发时更改标签。但除了蓝色数据外，其他所有数据都将与 'emphasis label' 重叠。
'avoidLabelOverlap' 不工作。
有办法吗？

这是一个例子

var option = {
  tooltip: {
    trigger: 'item'
  },
  legend: {
    top: '5%',
    left: 'center'
  },
  series: [
    {
      name: 'Access From',
      type: 'pie',
      radius: ['40%', '70%'],
      avoidLabelOverlap: false,
      itemStyle: {
        borderRadius: 10,
        borderColor: '#fff',
        borderWidth: 2
      },
      label: {
        show: true,
        position: 'center',
        formatter:  function (params) {
              var html = 'TEST';
              return html;
            }
      },
      emphasis: {
        label: {
          show: true,
          fontSize: '40',
          fontWeight: 'bold'
        }
      },
      labelLine: {
        show: false
      },
      data: [
        { value: 1048, name: 'Search Engine' },
        { value: 735, name: 'Direct' },
        { value: 580, name: 'Email' },
        { value: 484, name: 'Union Ads' },
        { value: 300, name: 'Video Ads' }
      ]
    }
  ]
};
