Flickering issue with Chart.js chart persists upon reopening the page

Utilizing mustache.js, I am injecting a view file into a designated <div>.

Within this view, I have incorporated a canvas element situated inside a specific div, showcasing a chart created with Chart.js.

<div>
    <canvas id="gesundheitsverlauf-chart">
        Your web-browser does not support the HTML 5 canvas element.
    </canvas>
</div>

The initial rendering of the chart occurs smoothly. However, upon navigating away and returning to the view, the chart flickers intermittently.

Despite deactivating animation and configuring the following settings:

responsive: true,
maintainAspectRatio: false,

I seek solutions to address the flickering issue.
Is there a method to validate whether the chart has been previously rendered on the canvas? If so, I would halt further drawing until requested by the user.

Answer №1

One potential reason for this issue could be that you are repeatedly redrawing the chart on the same div or canvas without first destroying it using .destroy();

For example, when creating a chart:

window.myChart = new Chart(ctx, options);

Make sure to destroy it before redrawing:

window.myChart.destroy();
