我有一个图表，需要从servlet提供的json中提取数据。

jsfiddle: http://jsfiddle.net/jeremybolanos/dcSUq/

，你可以看到它没有正确加载数据。我需要直接构建name:和data:字段吗?

我用的是:

var chart1 = {...}; // see jsfiddle link above
var cData = [];
var d = chart1.data;
for (var i in d) {
    var x = new Array(d[i].city, d[i].pph);
    cData.push(x);
}

看起来您需要将数据构建成正确的格式才能正常工作。如

series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]

ok -花了我30分钟回顾在javascript中构建数组，但这里是我的duh代码:

var cData = [];
var d = chart1.data;
for (var i in d) {
    var x = new Array();
    x['name'] = d[i].city;
    x['data'] = d[i].pph;
    cData.push(x);
}
