我尝试了几种类型的输出。我已经拥有的是：
JSON输出：

看起来不错！ 我在PHP上所做的工作是：
header("Content-type: text/json");
if($callback == 'cart-filling') {
// Count cart rows
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query
->select('*')
->from($db->quoteName('#__product_shoppingcart'))
->where($db->quoteName('date') . $scope);
$db->setQuery($query);
$results = $db->loadObjectList();
$ret = array();
foreach($results as $result) {
//$x = date_format($date, 'Y-m-d H:i:s');
$date = new DateTime($result->date);
$month = date_format($date, 'm');
$monthInt = (int) $month-1;
$date_part1 = date_format($date, 'Y');
$date_part2 = $monthInt;
$date_part3 = date_format($date, 'd');
$date_part4 = date_format($date, 'H');
$date_part5 = date_format($date, 'i');
$date_part6 = date_format($date, 's');
$formatted_date = (int) $date_part1 . ',' . (int) $date_part2 . ',' . (int) $date_part3 . ',' . (int) $date_part4 . ',' . (int) $date_part5 . ',' . (int) $date_part6;
/*
$date = new DateTime($result->date);
$x = date_format($date, "Y-m-d H:i:s");
*/
$x = $formatted_date;
$y = $result->qty;
//array_push($ret, array($x, $y));
//extract $row;
//$x = 'Date.UTC(' . $x . ')'; // convert from Unix timestamp to JavaScript time
$data[] = "[Date.UTC($x), $y]";
}
}
// Returning JSON string regarding the given callback and dtae
echo json_encode($data);
我的AJAX电话说：
function cartFilling() {
var url = 'components/com_product/views/reports/callback.php?callback=cart-filling&date='+date_scope;
jQuery.getJSON(url, function (data) {
Highcharts.chart('cartFilling', {
chart: {
zoomType: 'x'
},
title: {
text: 'Shopping Cart Filling Actions'
},
subtitle: {
text: document.ontouchstart === undefined ?
'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Carts Filled'
},
type: 'number'
},
legend: {
enabled: false
},
plotOptions: {
area: {
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: 'Cart Filling',
data: data
}]
});
});
}
所以，“数据”已经是：

此外， 我也尝试过序列化这些方法：
data: [data]
和
data: ([data])
最有趣的部分是，当我为“data：”手动插入生成的数据时，它可以工作。但是当我调用它的var时它什么也没做。我的四天浪费了！ 跟我有什么关系？这里发生了什么？我已经厌倦了等待，提出错误的问题，得到错误的答案并收到我的问题的负面评价:(请Highcharts的某位专家做出反应，否则我会用这台笔记本电脑做坏事！
谢谢
