从Highstock / Highcharts得到奇怪的错误信息

Question

我目前正在使用Hilitock/Highcharts，我不想通过json文件加载数据，我有。当我试图获取数据时，它会在控制台中给我这个我以前没有见过的错误信息:

highstock.js:456 Uncaught TypeError: f.data.slice is not a function

我试图通过这个函数获得json数据。当我输入我的data.json:

的url时，我才得到这个错误消息

$.each(names, function (i, name) {
        var dataUrl = 'http://local.priceservice.dev/js/data.json';
        $.getJSON(dataUrl,    function (data) {
            seriesOptions[i] = {
                name: name,
                data: data
            };
            // As we're loading the data asynchronously, we don't know what order it will arrive. So
            // we keep a counter and create the chart when all the data is loaded.
            seriesCounter += 1;
            if (seriesCounter === names.length) {
                createChart();
            }
            console.log(data)
        });
    });

我以前从未见过这个消息，我试着四处搜索，但我找不到和我有同样问题的人。

Json:

提前感谢!:)

series中的数据必须是数组。该系列至少需要一个对象，其数据格式如下:

series: [{
   data: [...] // <- has to be an array
}]

你的系列看起来像这样:

series: [{
   name: ...,
   data: { // <- you put an object instead of an array with points
      "priceSeries": ...
   }
}]

上面的代码导致slice调用对象，就像这样

var someObj = {};
someObj.slice(); // Uncaught TypeError: someObj.slice is not a function(…)

你应该这样做:http://jsfiddle.net/r3xfxymm/1/
