Answer 1

Try this,

<?php
    $chartData=array();
    for($i=0;$i<count($six_year);$i++) {
        $chartData[]=array('year'=>$six_year[$i]['year'],'visits'=>(int)$six_year[$i]['total']);
    }
    $chartData=json_encode($chartData);
?>
<script>
    var chart;
    var chartData ='<?php echo $chartData;?>';
</script>
