Google charts returning null in mysql query and loop

If I perform the query in the database it returns values, already in Charts it is returning null, what I am doing wrong ?

<?php
require("conexao.php"); //chama o arquivo de conexão ao BD
include("query_ti.php");
ini_set('display_errors', 0);
error_reporting(0);
?>

I saw the first mistake see if it solves

look for the line

echo "['".$row['TECNICO']."',".$row['CHAMADO']."],";

notes the closure of '

I think that’s how it would work

 echo "['".$row['TECNICO']."','".$row['CHAMADO']."'],";

even so I think this is not the whole error , you need to pass the html processing and not the source Cod. Run the script in the browser and display the source Cod and copy it here in another box to see what your php is printing ( after replacing the line I fzlei )
