here is my code.

google.charts.load('current', {'packages':['corechart']});

function drawChart() {
var data = google.visualization.arrayToDataTable([
  ['Month','Running'],
  <?php
    for($month=$fromdv;$month<=$todv;$month++){
        $monthv = date('M',strtotime($year[0].'-'.$month.'-1'));
        $fd = date('Y-m-d',strtotime($year[0].'-'.$month.'-1'));
        $td = date('Y-m-t',strtotime($fd));
        $running = get_running($team,$fd,$td,'alldevice','overall');
        echo "['".$monthv."',".$running."],";
    }
    ?>
]);

var options = {
  title: 'MOBILE APP SALES',
