i am passing data like this
$chart->series[] = array(\'data\' => array()); in array i have data in string 1 => string \'11:03:01\' (length=8) 2 =
process the array with times in a loop and add each item to a variable that is seperated by comma..
then finally put
series: []
assuming $str contains values:
$str = "'11:03:01', '11:07:56'";
