Bar Chart - Add Percentage to the Value Label

[Ophir_Buchman]

When creating a column chart you might want to add a percentage value next to the actual value

Add the following script to your widget:

widget.on('processresult', function(widget,result) { 
  result.result.plotOptions.series.dataLabels.formatter = function() { 
    total = 0
    this.series.data.forEach(function(datapoint) { total += datapoint.y })

    percent = (100 * this.y) / (total);
    percent = percent.toFixed(1);

    return this.y + '<br/>(' + percent + '%)'
  }
})

Before	After

Thank you for producing this code.  This is a feature I have been trying to figure out for a while.  Can you please provide some additional detail? I am a user with minimal script/coding experience.  Is this script inserted into the script editor or directly into the sql code for the widget?  Also, are there variables within this code that need to be changed for the specific widget data it is inserted into?  Thank you.
