高图表记录限制

Question

我不想为此图表设置限制。

如何删除它才能工作？

代码：

$sql = "(SELECT (UNIX_TIMESTAMP(timestamp)*1000) AS time ,IFNULL(hodnota,'null')AS temperature
                FROM arduino_data ORDER BY timestamp DESC LIMIT 60) ORDER BY time ASC";
$result = $conn->query($sql);
 
if ($result->num_rows>0){
$count =0;
echo '[';
while($row=$result->fetch_assoc()){      
      echo '['.$row["time"].',' .$row["temperature"].']';
      $count++;
       if ($count<"60"){
       echo ',';
       }      
     }
     echo ']';
}else{
echo "[[],[]]";
}
$conn->close();
