Template node and chartjs data problem

I read a lot of forum post about this topic like
I am trying to get an array of data to my primitive line chart expecting a data like this

[1, 2, 3, 4, 5]

I don't have any problem unless I try to use real data on my chart
I am getting this number from an api as a realtime number then I combine them with join node to make an array of 5 numbers, I can get the combined payload with

{{msg.combine}}

then I try to write contents of msg.combine to var combinegelen
but I stuck on this stage

can someone point me to the right direction about this situation,
thanks alot.
:v:
here is my template node code

<script>
    const chartOptions = {
    maintainAspectRatio: false,
    legend: {
        display: false,
    },
    tooltips: {
        enabled: false,
    },
    elements: {
        point: {
            radius: 0
        },
    },
    scales: {
        xAxes: [{
            gridLines: false,
            scaleLabel: false,
            ticks: {
                display: false
            }
        }],
        yAxes: [{
            gridLines: false,
            scaleLabel: false,
            ticks: {
                display: false,
                suggestedMin: 0,
                suggestedMax: 10
            }
        }]
    }
};
//
var gelendata = [0, 5, 5, 5, 10],
var ctx = document.getElementById('chart1').getContext('2d');
var chart = new Chart(ctx, {
    type: "line",
    data: {
        labels: [1, 2, 1, 3, 5],
        datasets: [
            {
                backgroundColor: "rgba(101, 116, 205, 0.1)",
                borderColor: "rgba(101, 116, 205, 0.8)",
                borderWidth: 2,
                data: gelendata,
            },
        ],
    },
    options: chartOptions
});

    
</script>
<script>
(function(scope) {
  scope.$watch('msg', function(msg) {
    if (msg) {
      var gelendata = msg.combine;
    }
  });
})(scope);
</script>             
<style>
.charticin {
height:75px;

}
</style>
 <div class="charticin"><canvas id="chart1" height="75"></canvas></div>
         

here is my flow its actually bigger than this,
