Javascript 如何使用Higcharts插件在饼图中显示百分比和计数值？

我试着用下面的方法用PHP的Highchart插件绘制饼图

---

在上面的饼图中，我想在饼图中显示百分比和计数2，如A:67.0%（2）和B:33.0%（1）

highcharts饼图有一个选项，用于为数据标签设置您自己的格式化程序。看

在其中，您可以访问：

this.percentage     Stacked series and pies only. The point's percentage of the total.
this.point      The point object. The point name, if defined, is available through this.point.name.
this.series:    The series object. The series name is available through this. series.name.
this.total     Stacked series only. The total value at this point's x value.
this.x:   The x value.
this.y:   The y value.
