อยากทราบวิธีการปรับ scale กราฟของแกน x และแกน y แล้ววิธีปรับขนาดหน้าเว็บไซด์ให้เข้ากับขนาดของจอคอมแล้วโทรศัพท์ครับ

<?php
            $query = "
SELECT DATETIME AS date, A
FROM xxxxx
            GROUP BY ID
            ";
$result = mysqli_query($con, $query);
$resultchart = mysqli_query($con, $query);  

 //for chart
$id = array();
$A = array();
$date = array();

while($rs = mysqli_fetch_array($resultchart)){ 
  $id[] = "\"".$rs['id']."\""; 
  $A[] = "\"".$rs['A']."\"";
  $date[] = "\"".$rs['date']."\""; 
}
$id = implode(",", $id); 
$A = implode(",", $A);
$date = implode(",", $date);   
            ?>
