我是JSON和High Charts的新手。我需要显示带有高图表的动态线条。我正在使用JSON格式。我真的很困惑我的代码中出了什么问题。我没有在Firebug中收到任何错误，但图表没有渲染。下面是我的JSON。

这是我的html文件。
<script src="jquery.min.js" type="text/javascript"></script>
<script src="highcharts.js"></script>
<div id="errq" style="height: 400px"></div>
<script>
$(document).ready(function() {
var options = {
chart: {
renderTo: 'errq',
type: 'line'
},
title: {
text: 'shannon.way'
},
tooltip: {
formatter: function() {
return this.series.name + ':' + '<b> ' + this.y + '</b>';
},
style: {
fontSize: '10px'
}
},
credits: {
enabled: false
},
yAxis: {
title: {
text: ''
},
},
xAxis: {
labels: {
enabled: false
}
},
series: [{
name: 'Budget Spent',
data: []},
{
name: 'Impressions',
data: []},
{
name: 'Clicks',
data: []},
{
name: 'Likes',
data: []}
]
};
$.getJSON('accounts.json', null, function(data) {
var str = JSON.stringify(data);
/* options.series[0].data = data[0].CLImp;
options.series[1].data = data[0].CLClick;
options.series[2].data = data[0].CLSpent;
options.series[3].data = data[0].CLLikes;
chart = new Highcharts.Chart(options);*/
var json_parsed = $.parseJSON(str);
var CLimp = new Array();
for (var u = 0; u < json_parsed.data.length; u++) {
var user = json_parsed.data[u];
for (i = 0; i < user.Campaign.length; i++) {
CLimp[i] = parseInt(user.Campaign[i].CLImpression);
}
}
var imp = CLimp.join(",");
alert(imp);
options.series[0].data = imp;
chart = new Highcharts.Chart(options);
});
});
</script>
当我alert(imp);时，我得到78,90,0,0,0,0,0,2786134,0,0但无法弄清楚为什么图表不会呈现。请你就此提出建议。
答案 0 :(得分：1)
Highcharts不希望数据采用字符串格式，而是采用数组格式。您的问题是您将数组转换为字符串：
var imp = CLimp.join(",");
alert(imp);
options.series[0].data = imp;
直接使用数组，它应该可以工作：
options.series[0].data = CLimp;
