Thanks to all, now i have the data in order, I have only one other problem, I'm trying to store rows every time into a column array, and i need to refresh this array every time the timestamp change of 20 ms. Because of inside the DB every row of the columns has a different value every 20 millisecond (so inside the column of DB for every timestamp I have 29 rows and if i scroll down the column i have new 29 rows with new timestamp increased of 20 ms)
