I made a chart that shows machines and the times that was taken for them to be fixed (machines X, time Y)
the data is loaded dynamically via mysql like the following
<?php
include_once(“connexion.php”);
ini_set(‘max_execution_time’,300);
//ini_set(‘error_reporting’, E_ALL);
$sq = “select machine,date_tech,time(time_fin – time_deb) as diff from action_archiv_tech WHERE (date_tech BETWEEN ‘2018-09-10’ AND ‘2018-10-06’)”;
$r = mysql_query($sq) or (die(mysql_error()));
while($tab = mysql_fetch_assoc($r)) {
$machine = $tab[‘machine’];
$diff = $tab[‘diff’];
// $data[] = [“label”=>$machine, “y”=>$diff];
$data[] = array(
‘label’ => $tab[‘machine’],
‘y’ => $tab[‘diff’]
);
}
?>
