PHP - 如何在类别highcharts上显示数据库中的数据？

Question

我有问题。如何在类别highcharts上显示数据库中的数据？我使用组合双轴。我需要这个大学毕业。有人能帮我吗？

我用过这个

var data = {"name":"Percentage","data":[50,28,150,125,34,75]};
var categories = [<?php echo join($nama_tugas, ",") ?>];

但它不起作用

$i = mysql_query("SELECT * FROM tbl_detail_tugas WHERE kode_mapel='$km' AND nip ='$nip'");                                    
while ($u = mysql_fetch_assoc($i)) {
    $d = $u['detail_id'];        
    echo  $d ;
    $a = mysql_query("SELECT AVG(nilai) AS jum FROM tbl_nilai WHERE tbl_nilai.detail_id = $d");
    while ($t = mysql_fetch_array($a)) {
        echo $t['jum'];
        $k[] = $t['jum'];                                               
     }


}

$aa = mysql_query("SELECT * FROM tbl_detail_tugas WHERE kode_mapel='$km' AND nip ='$nip'");

while ($uu = mysql_fetch_array($aa)) {
    $dd = $uu['detail_id'];

    $nama_tugas = $$uu['nama_tugas'];

    $ii = mysql_query("SELECT * FROM tbl_nilai WHERE tbl_nilai.detail_id = $dd AND nis ='$id'");
    while ($tt = mysql_fetch_array($ii)) {
        echo $tt['jum'];
        $kk[] = $tt['nilai'];                                               

    }


}
