jquery – 无法删除highcharts中的所有“系列”

我不确定我的代码是怎么回事,但是在我深入研究之后我无法删除highcharts中的所有系列.当我调用resetChart函数时,它只删除4个系列中的2个,我设置了一个临时警报,告诉显示它的删除内容,它只警告2个系列.

但是,当我删除行chart.series [i] .remove();所有4个警报都有效.
我已经尝试了一些循环数组的方法,甚至把它反过来但它没有任何区别.

如果你将下面的代码复制到jsfiddle,你会看到我的意思

HTML

<div id="container" style="height: 400px; min-width: 600px"></div>
<script type="text/javascript" src="http://www.highcharts.com/js/tesTing-stock.js"></script>
<script type="text/javascript" src="http://www.highcharts.com/samples/data/usdeur.js"></script>

JQuery的

$(function() {
var chart;

var colors = Highcharts.getOptions().colors,categories = ['October','November'],name = 'Monthly',data = [{
        y: 22,drilldown:[{
            name: 'Income',data: [12,0],categories: ['Income','Expenses']
        },{
            name: 'Expenses',data: [0,5]
        },{
            name: 'employee',3]
        },{
            name: 'Tax Office',1]
        }]
    },{
        y: 21
    }];
function setChart(drilldown) {
    $.each(chart.series,function(i,val) {
        val.remove();
    });
    if(drilldown) {
        chart.xAxis[0].setCategories(drilldown[0].categories);
        $.each(drilldown,val) {
            chart.addSeries({
                 name: val.name,data: val.data
            },falsE);
        });
    }

    chart.redraw();
}
function resetChart() {
    //chart.toolbar.remove('RESET');
    $.each(chart.series.reverse(),function(i) {
        alert('removing :' + chart.series[i].Name);

        // IF I REMOVE THE BELOW LINE,ALL ALERTS DISPLAY CORRECTLY
        chart.series[i].remove();
    });

     chart.xAxis[0].setCategories(categories);

while(chart.series.length > 0)
 chart.series[0].remove();
