Question

我是AmCharts的新手，无法显示我需要的简单图表。我使用了AmCharts实时编辑器中的代码。这是PHP文件（getGred.php）

   $query = "SELECT gred, COUNT( gred ) AS bilangan FROM borg_peribadi GROUP BY gred";
$result = mysql_query( $query );
//echo $query;
//echo "<br>";
$rows = array();
while ($data = mysql_fetch_assoc ($result)){
     $rows[] = array(
    "gred" => $data[ 'gred' ],
    "bilangan" => $data[ 'bilangan' ]
  );
  }

  echo json_encode( $rows );

这就是我从AmCharts教程中得到的：

    <body>
        <div id="chartdiv" style="width: 100%; height: 400px; background-color: #FFFFFF;" ></div>
    </body>
</html>

问题不是图表没有显示，只显示在下面：output

希望得到任何错误或错误的指示。谢谢。

编辑：我已经添加了getGred.php的输出

[{＆＃34; GRED＆＃34;：＆＃34; 29＆＃34;＆＃34; bilangan＆＃34;：＆＃34; 1＆＃34;}，{＆＃34; GRED＆＃34 ;：＆＃34; 41＆＃34;＆＃34; bilangan＆＃34;：＆＃34; 5＆＃34;}，{＆＃34; GRED＆＃34;：＆＃34; 44＆＃34;，＆＃34; bilangan＆＃34;：＆＃34; 6＆＃34;}]

使用dataloader将php / mysql数据加载到amcharts
