Add series total to legend in Highcharts
提问by Mike
Using Highcharts.js - I want to add the series total to the legend (where it currently says '12345'). I know enough that I need to write a labelFormatter function, but I don't know enough JavaScript to figure out how to sum up the total of each series. Code is below (also live version here: http://jsbin.com/ukabob/8).
使用 Highcharts.js - 我想将系列总数添加到图例中（当前显示为“12345”）。我知道我需要编写一个 labelFormatter 函数，但我对 JavaScript 的了解不够，无法弄清楚如何总结每个系列的总数。代码如下（这里也是实时版本：http: //jsbin.com/ukabob/8）。
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({

A more generic & dynamic answer:
一个更通用和动态的答案：
legend: {
labelFormatter: function() {
var total = 0;
for(var i=this.yData.length; i--;) { total += this.yData[i]; };
return this.name + '- Total: ' + total;
}
}

Figured it out. I added the total to the series, then called it with this.options. See updated code below:
弄清楚了。我将总数添加到系列中，然后使用 this.options 调用它。请参阅下面的更新代码：
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">(Total: ' + this.options.total + ')</span>';
}
},
series: [{
name: 'Honeywell',
total: 9150,
data: [700,725,750,850,950,1000,1025,1050,1050,1050]
}, {
name: 'Bombardier',
total: 10548,
data: [661,758,880,990,1065,1136,1193,1241,1289,1335]
}, {
name: 'Embraer',
total: 9301,
data: [747,789,839,861,890,908,984,1030,1097,1156]
}]
});
});
