ช่วยดูโค้ดการแสดงกราฟเป็นภาษาไทยครับ ขอบคุณครับ

$SQL="SELECT * FROM regis";
$sqlquery=mysql_db_query($dbname,$SQL);
$num_rows =mysql_num_rows($sqlquery);

$i=0;
while($row=mysql_fetch_array($sqlquery))
{
$xdata[$i]=$row["run"];
$ydata[$i]=$row["value"];
$i++;
}
$r=$xdata;
$s=$ydata;
แทนค่าแบบนี้ถูกต้องไหมครับ
