Highcharts / PHP / JS新手在这里。我无法格式化所需的数据数组（$ data）以输入Highcharts。嵌入式php代码输出表单的日期时间/十进制数据数组
[1388680500000, 11215], [1388680800000, 11334], [1388681100000, 11487], [1388681400000, 11600], [1388681700000, 11641], [1388682000000, 11648], [1388682300000, 11692], [1388682600000, 11641], [1388682900000, 11715], [1388683200000, 11808], [1388683500000, 11845], [1388683800000, 11813], [1388684100000, 11771], [1388684400000, 11746], [1388684700000, 11808], [1388685000000, 11784], [1388685300000, 11727], [1388685600000, 11608], [1388685900000, 11648], [1388686200000, 11587], [1388686500000, 11555], [1388686800000, 11596], [1388687100000, 11541], [1388687400000, 11441], [1388687700000, 11393], [1388688000000, 11340], [1388688300000, 11152], [1388688600000, 11031], [1388688900000, 10920], [1388689200000, 10681], [1388689500000, 10221], [1388689800000, 9895]
我目前正在手动将这些数据（在[]中）复制到series：data：字段中，该字段成功生成图表（见下文）。我试图用系列替换数据字段：[{data：[]但是不再创建图表。 （根据http://www.highcharts.com/docs/working-with-data/preprocessing-data-from-a-database）
我也在php和JS中尝试过json_encode（$ data）的多次迭代，但无济于事。我非常感谢能够向我展示PHP输出到Highcharts数据字段的确切翻译的人，最好是使用JSON。

编辑：
我已经将脚本重新调整为以下格式，但是图表根本不再绘制...我确信JSON格式是正确的。请帮忙！

尝试使用以下代码从MYSQL获取记录并将其转换为高级数据。
setup.js
var chart;
$(document).ready(function() {
var cursan = {
chart: {
renderTo: 'current_sanand',
defaultSeriesType: 'area',
marginRight: 10,
marginBottom: 20

categories: ['Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'Jan', 'Feb', 'Mar']
},
yAxis: {
title: {
text: 'Amount [Billion]'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
crosshairs: true,
shared: true

}
},
series: [{

marker: {
fillColor: '#FFFFFF',
lineWidth: 2,
lineColor: null // inherit from series
},
dataLabels: {

}
}
}],
}
$.getJSON("data.php", function(json){
options.xAxis.categories = json['category'];
options.series[0].name = json['name'];
options.series[0].data = json['data'];
chart = new Highcharts.Chart(options);
});
});
data.php
$ con = mysql_connect（“localhost”，“root”，“”）;
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("test", $con);
$sql = mysql_query("SELECT unix_timestamp(DATETIMES), TEST FROM PT");
$result['name'] = 'Sales Summary';
while($r = mysql_fetch_array($sql)) {

}
print json_encode($result);

我尽力而为，这种方法运作正常。试试吧。
