Question

我在postgresql数据库中查询数据，并以JSON格式打印结果：

服务器/ PHP：

$result = array();
$result['name'] = 'serie1';
while($r = pg_fetch_array($query)) {
     $result['category'][] = $r['day'];
     $result['data'][] = $r['temperature']; 
}
$json = array();
array_push($json,$result);
print json_encode($json);

JSON outoput：

[{＆＃34;类别＆＃34;：[1,2,3,4,5]，＆＃34;数据＆＃34;：[25,30,33,13,16]} ]

对于简单的高图，我的JSON输出不是正确的，或者在PHP的SQL结果准备好之前呈现图形！

何时我可以在JSON响应准备就绪后呈现图形以及如何将格式设置为高图结构？

客户端/ HTML：

撕掉高图，等待getJSON响应PHP
