change context after the response in sent in django

I have a django view and I'm expecting some of the data in the context to change a few times a second. Can I load a new context into the template after the response is sent without sending a new request? Thanks.

the view

def debug(request):
    return render(request, 'all/debug.html', context={"x": x, "y": y})

the template

<div class="container">
    <canvas id="data"></canvas>
    <div class="graphing">
    <select class="graph-select"></select>
    <canvas id="graph" width="500"></canvas>
    </div>
</div>

<script>
    let y = "";
    let x = ""
    Chart.defaults.global.animation.duration = 0;
    var ctx = document.getElementById('graph').getContext('2d');
    var chart = new Chart(ctx, {
        // The type of chart we want to create
        type: 'line',

        // The data for our dataset
        data: {
            labels: x.split` `.map(n => +n),
            datasets: [{
                label: 'My First dataset',
                backgroundColor: 'rgb(255, 99, 132)',
                borderColor: 'rgb(255, 99, 132)',
                data: y.split` `.map(n => +n)
            }]
        },

        // Configuration options go here
        options: {
            responsive: false,
        }
    });

</script>

What I want is to dynamically change the x and y data without sending a new request
