Javascript Error when filtering

Dashboard Designer SharePoint 2013/2016, Office 365 versions
1

Hi,

I followed the example here: spchart.com/demo/helpdesk-dashboard, where you select a value from a dropdown, and the charts below filters.

I am using column chart, and everything works on Firefox and Chrome, but not IE 11. When I select a value from the dropdown, it only works on every second selection.

Example:

On page load -> chart renders
Select option A -> No chart
Select option C -> chart renders
Select option B -> no chart
Select option A -> chart renders

I get the following error in console when chart doesn't render:
Rendering failed: TypeError: Unable to get property 'removeChild' of undefined or null reference.
See screenshot for complete console log.

Please let me know how to fix this.

Thanks.

Hi,
Please, try to replace handlers.finish function:

[code]handlers.finish = function (data, logger, processor, el) {
logger.debug('Data is processed: ', data);

if (processor && !processor.subscribed) {
    $('#helpdesk-agents').change(function () {
        el.empty().html('<img alt="loading..." src="/_layouts/15/images/gears_anv4.gif" />');
        processor.process(el);
    });

    processor.subscribed = true;
}

return true;

}[/code]
