JavaScript – 在Highcharts中添加系列总数到图例

使用Highcharts.js – 我想添加系列总数到图例(它当前说’12345′).我知道我需要写一个labelFormatter函数,但我不知道足够的 JavaScript来弄清楚如何总结每个系列的总和.代码在下面(也是现场版本： http://jsbin.com/ukabob/8).

$(function () {
var chart;
$(document).ready(function() {
    chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container',type: 'line',BACkgroundColor: '#E9E7DC',borderRadius:0,margin: [0,150,30,0]
        },colors: ['#A74B59','#46C4B7','#EDBA70'],credits: {
          enabled: false
        },title: {
            text: null
        },xAxis: {
            categories: ['2013','2014','2015','2016','2017','2018','2019','2020','2021','2022'],gridLineWidth:1,gridLineColor: '#FFFFFF',labels: {
              style: {
                color: '#000000'
              },formatter: function() {
                return '<div style="font-size:22px; font-family: \'Advent Pro\',sans-serif;">'+
                    this.value +'</div>';
              },y:25
            },lineColor: '#FFFFFF',tickColor: '#FFFFFF',tickLength: 30
        },yAxis: {
            gridLineWidth:0,title: {
                text: null
            },labels: {
              enabled: false
            }
        },plotOptions: {
          series: {
            marker: {
                radius: 6,lineWidth: 2,lineColor: null,// inherit from series
                symbol: 'circle',states: {
                    hover: {
                        fillColor: '#E9E7DC',radius:6
                    }
                }
            },states: {
              hover: {
                lineWidth:4
              }
            }
          }
        },tooltip: {
            borderWidth:0,borderRadius: 0
            },legend: {
          borderRadius:0,BACkgroundColor: '#FFFFFF',itemMarginBottom: 7,layout: 'vertical',align: 'right',verticalAlign: 'top',y: 30,x: 2,borderWidth: 0,width:130,symboLPADding: 10,useHTML:true,shadow: {
              color: '#000',width: 3,opacity: 0.15,offsetY: 2,offsetX: 1
            },labelFormatter: function() {
              return '<div class="' + this.name + '-arrow"></div><span style="font-family: \'Advent Pro\',sans-serif; font-size:16px">' + this.name +'</span><br/><span style="font-size:10px; color:#ababaa">(@R_102_10586@l: 12345)</span>';
        }

        },series: [{
            name: 'Honeywell',data: [700,725,750,850,950,1000,1025,1050,1050]

        }]
    });
});

});

legend: {
   labelFormatter: function() {
      var @R_102_10586@l = 0;
      for(var i=this.yData.length; i--;) { @R_102_10586@l += this.yData[i]; };
