不幸的是，我们仍然没有实现这样的功能，因为它没有在我们的UserVoice平台上获得足够的选票，但一切都没有失去。
下面是一个可以帮助你自己做的例子：http://jsfiddle.net/Lcnon9ss/。该示例基于pie系列类型，但它应该很快就能满足您的要求。
此外，您可以在上面提到的UserVoice平台上对该功能进行投票，以下是链接：https://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/34591699-ability-to-write-the-labels-of-the-sunburst-chart
此致！

我遇到了同样的问题，我通过为数据标签添加textPath解决了该问题，如下所示：

...series:[ ...
  dataLabels: {
    textPath: {
      enabled: true,
      attiributes: {
        startOffset: '10%',
        textAnchor: 'start',
      }
    }
  }

您可以根据需要调整参数“startOffset”和“textAnchor”。
