}

UPDATE
更新
Here is what I'm trying to do:
这是我想要做的：
var chart;
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
zoomType: 'x'
},
yAxis: {
type: 'double',
min: 0
},
xAxis: {
type: 'datetime',
labels: {
formatter: function () {
return Highcharts.dateFormat('%a %d %b %H:%M', this.value);
},
dateTimeLabelFormats: {
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'
}
}
},
series: [{
name: 'MyData1',
data: []
}, {
name: 'MyData2',
data: []
}]
});
chart.series[0].setData([
[Date.UTC(2013, 0, 1, 08, 00), 4.4],
[Date.UTC(2013, 0, 1, 12, 00), 6.0],
[Date.UTC(2013, 0, 1, 17, 00), 7.7],
[Date.UTC(2013, 0, 1, 22, 00), 5.8]
]);
chart.series[1].setData([
[Date.UTC(2013, 0, 1, 08, 30), 0.4],
[Date.UTC(2013, 0, 1, 10, 00), 0.0],
[Date.UTC(2013, 0, 1, 16, 00), 0.7],
[Date.UTC(2013, 0, 1, 20, 00), 0.8]
]);
});
hereis it in jsFiddle.
这是在 jsFiddle 中。
var datatype1=[];
var datatype2= [];
for(index in userReadingsJsonCollection.items){
if(userReadingsJsonCollection.items[index].ReadingsData.Reading_Type==type1){
datatype1.push(
[Date.parse(userReadingsJsonCollection.items[index].ReadingsData.Rec_DateTime),
userReadingsJsonCollection.items[index].ReadingsData.Reading]
);
}
if(userReadingsJsonCollection.items[index].ReadingsData.Reading_Type==type2){
datatype2.push(
[userReadingsJsonCollection.items[index].ReadingsData.Rec_DateTime,
userReadingsJsonCollection.items[index].ReadingsData.Reading]
);
}
}
The result I get is [[1357027200000,5.5]] and this works great.
我得到的结果是 [[1357027200000,5.5]] 并且效果很好。

If your time is already UTC then it's as simple as:
如果您的时间已经是 UTC，那么它很简单：
Date.parse("01/01/2013 08:00")

Assuming your data comes back as valid JSON:
假设您的数据作为有效的 JSON 返回：
var jsonObj = {value:"01/01/2013 08:00", key:5.5};
var seriesOneData = [];
seriesOneData.push([Date.parse(jsonObj.value),jsonObj.key]);
