高圖不顯示區域範圍在圖例中

我無法讓Highcharts在圖例的圖例中顯示我的區域範圍系列。我在這裏有一個jsFiddle：http://jsfiddle.net/0eaj4ceu/它顯示了這個問題。它僅在圖例中顯示單行，而區域範圍系列未顯示。有任何想法嗎？下面高圖不顯示區域範圍在圖例中

代碼：

HTML：

<script src="http://code.highcharts.com/highcharts.js"></script> 
<script src="http://code.highcharts.com/highcharts-more.js"></script> 
<script src="http://code.highcharts.com/modules/exporting.js"></script> 

<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

JS：

$(document).ready(function() { 
initChart(); 
}); 

function initChart() {
