计算高图中每个系列的百分比值

Question

我正在尝试计算每个系列的百分比值，我设法找到的功能类似于

 formatter:function() {
                    var pcnt = (this.y / dataSum) * 100;
                    return Highcharts.numberFormat(pcnt) + '%';
                }

但让我感到困惑的是，我怎样才能动态地创建这个函数，以便它可以应用于提供的每个系列对象

强调上面函数的dataSum。我尝试使用谷歌搜索以防万一 highcharts 已经在他们的文档中提供了一些解决方案，但遗憾的是我没有找到任何东西，我唯一发现的是将已经提供的值与 + '%' 连接起来，这远远超出了百分比的实际值该特定系列

$(function() {
  var chart = new Highcharts.Chart(

有没有人尝试过在任何情况下都提供系列百分比值的解决方案？我正在尝试计算 total_children 的百分比和 num_cars_owned 系列的百分比，因为它们是系列数组的分离对象。

您可以在 link 此处找到代码示例 http://jsfiddle.net/JeLrb/538/

Answer 1

您需要计算dataSum值：

        tooltip: {
            ...,
            formatter: function() {
                var dataSum = 0,
                    pcnt;

                this.series.points.forEach(function(point) {
                    dataSum += point.y;
                });

                pcnt = (this.y / dataSum) * 100;

                return Highcharts.numberFormat(pcnt) + '%';
            }
        }
