Make Amcharts work in WordPress tabs

Hi,
I′d like to use Amcharts shortcodes to display some charts in multiple tabs on a single page.

The first chart [amcharts id=”chart-1″] displays in the first div as expected.

However, clicking on subsequent tabs reveals blank divs. The charts won′t display.

***
The documentation provides an explanation here:
https://www.amcharts.com/docs/v3/tutorials/displaying-charts-in-tabs-or-other-dynamic-page-elements/
and a fiddle: https://jsfiddle.net/amcharts/mZ2Gq/

So guessing that this chart.invalidateSize code should go in the javascript input field for the Amcharts wordpress plugin. Something like this perhaps?

$(function() {
      $( "#tab" ).tabs({
        select: function(event, ui) {
          console.log('Calling chart.invalidateSize()');
          chart.invalidateSize();
        }
      });
    });

Using that code example creates an a TypeError in the javascript console.

What code is needed to make it run correctly in WordPress?
