如何在饼图中使用Higcharts插件显示百分比和Count值？

Question

我尝试了使用Highchart插件和PHP绘制饼图的方法

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

Answer 1

highcharts饼图可以选择为数据标签设置自己的格式化程序。见https://api.highcharts.com/highcharts/plotOptions.pie.dataLabels.formatter

在那里你可以访问：

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.
