Unable to display dynamic data in IE8

[JackQChen]

Expected behaviour

display dynamic data in IE8

Actual behaviour

unable to display dynamic data in IE8

Live demo with steps to reproduce

I get the archive from official website,in examples\dynamic-update , I import the oldie.js after highcharts.js,but still cann't display dynamic data in IE8.
I noticed that if i invoke addPoint method like "series.addPoint([x, y], true, true);",charts will not be updated,but if i set the third parameter (shift) to false,charts will be updated,but the first point will not be removed.
Thanks！

Hi @chen365409389

Thank you for reporting the issue. Does it mean other browsers (e.g. Chrome) works fine? Do you see the same issue in our official demo: https://www.highcharts.com/demo/dynamic-update

[JackQChen]

yes,it works fine in Chrome and IE9, but got issue in old IE browsers(IE6,IE8).
I open the official demo url in IE9, it tips need add oldie.js , so I download the latest archive from https://code.highcharts.com/zips/Highcharts-6.1.2.zip , and got the same issue
Thanks

@KacperMadej - could you take a look?

It's a bug in H.indexOfPolyfill in oldie. The function there is wrongly called or just not as it should be.

As a workaround:

use this code after loading oldie and before creating any charts:

Highcharts.indexOfPolyfill = function (member, fromIndex) {
    var arr = this,
        len,
        i = fromIndex || 0;

    if (arr) {
        len = arr.length;

        for (; i < len; i++) {
            if (arr[i] === member) {
                return i;
            }
        }
    }

    return -1;
};

Internal note:
Resolve this with #8346 too
