php 및 highcharts api.but를 사용하여 내 데이터베이스에 저장된 결과를 인쇄하려고하는데 그래프가 화면에 표시되지 않습니다. 축도 표시됩니다. 데이터는 mysql database.i에서 가져옵니다. highcharts 데모와 같은 코드이지만 운이 없다.
heres my code그래프를 표시하지 않는 하이 차트
<?php
require_once ('connection.php');
session_start();
$username = $_SESSION['username'];
$quizes=null;
$score=array();
$i=0;
$result = mysql_query("SELECT * FROM `score` WHERE `username`='$username'") or die(mysql_error);
while($rows=mysql_fetch_array($result)) {
$quizes= $quizes. "'".$rows['quiz']."',";
$score[$i]=$rows['score'];
$i=$i+1;
}
print_r($score);
echo $quizes;
?>
