How do I export a chart as a high-quality image?

Struggling a bit to find an answer to this.

Can anyone suggest a way to create a sharp, high-quality image export from my charts?

At this point I've converted my SimpleXML dashboard into HTML and tried to convert my div/chart SVG into a PNG file. This was partially successful but the quality of the exported image was awful.

Any help much would be much appreciated.

Hi there @peamc, yes there is a way to do this using HTML2Canvas:

    <script src="https://rawgithub.com/niklasvh/html2canvas/master/dist/html2canvas.min.js"></script>
    <script type="text/javascript">


        function exportChart() {

            html2canvas($('#element1'), {
                useCORS: true,
                allowTaint: true,
                  onrendered: function (canvas) {
                    var img = document.createElement("a");

                    img.href = canvas.toDataURL();
                    img.download = "chart.png";
                    img.click();

                      }
                  });
              } 
</script>

Heres a function which does what you need, just replace 'element1' with the div id of you div containing your chart!
Good luck mate.
