Display total records in Pie Chart

[randybow]

I am sure this is something easy I am missing, but I can't figure it out. I would like to display somewhere in the pie chart the total number of records In all categories. I do see that I can convert the individual slice values to percentages, but I can't figure out how to display a total number represented in the chart. Is this possible?

Hello @randybow

It is possible to implement such a workflow using additional JS code.
You need to add Header/Footer to your chart and then insert the following snippets of code:

HEADER

<script type="text/javascript">

var myVar = setInterval(myTimer, 1000);

function myTimer() {
 if(Highcharts) {
  const options = Highcharts.charts[0].series[0].yData;
  const result = options.reduce(function(accumulator, currentValue) {return accumulator + currentValue});
  document.getElementById('total').innerHTML = 'Total: ' + result;
  myStopFunction();
 }
 return null;
}

function myStopFunction() {
  clearInterval(myVar);
}

</script>

FOOTER

<h1 id="total"></h1>

Please note that you need to disable the HTML editor both in the header and footer. You can do this in the advanced section.

Much appreciated @Hastur. This script worked perfectly! Sorry I took so long getting back to this.
