数组在Chartjs中无法正常工作

Question

I'm doing a data integration project with my external ERP(Tally.ERP9) with PHP(version 7),JQuery and ChartJS. where I'm pulling data from Tally.ERP9 through ODBC and fetched the rows as array. I also converted PHP array Variable as JavaScript array Variable using the below code

<script type="text/javascript">
var test = '<?php 
    $stks = array_values($stocks);
    echo json_encode($stks);

 ?>';

var test2 = '<?php 
    $qtys = array_values($qty);
    $armap = array_map('intval', $qtys);
    echo json_encode($armap);

?>';</script>

Then I'm calling variable in JavaScript like below,

        $(document).ready(function(){
        var ctx = $("#pie-container").get(0).getContext("2d");

        alert(test);
        alert(test2);

        var data = {
      labels : test,
datasets: [
    {
        label: "My First dataset",
        fill: true,
        lineTension: 0.1,
        backgroundColor: "rgba(75,192,192,0.4)",
        borderColor: "rgba(75,192,192,1)",
        borderCapStyle: 'butt',
        borderDash: [],
        borderDashOffset: 0.0,
        borderJoinStyle: 'miter',
        pointBorderColor: "rgba(75,192,192,1)",
        pointBackgroundColor: "#fff",
        pointBorderWidth: 1,
        pointHoverRadius: 5,
        pointHoverBackgroundColor: "rgba(75,192,192,1)",
        pointHoverBorderColor: "rgba(220,220,220,1)",
        pointHoverBorderWidth: 2,
        pointRadius: 1,
        pointHitRadius: 10,
        data: test2,
        spanGaps: false,
    }
]};
        var piechart = new Chart(ctx,{type:'line',data:data});
    });

while alerting its giving the desired array as Output,



but when passing them as array to the chartJS, Its throwing the following error.


Please suggest me where I'm doing mistake. But I'm sure the chart.js is working with sample array that I made myself as hard coded.

Please Guide me how to achieve the above chart by passing the array variable in Chartjs, Thanks in Advance!
