Displaying percentage inside pie item for highcharts

问题

I am trying to figure out if it is possible to display the percentage for each pie item inside the actual pie item for highcharts? Example of what I mean is something like this:

回答1:

You may want to look @ dataLabels.formatter. this.percentage option is available for pie

Also dataLabels.distance can be set to a negative value for dataLabels inside the pie.

Its suprisingly easy. In your tooltip or dataLabels section change your format.

FROM:
  format: '<b>{point.name}</b>: {point.y:.1f} Rs.',
TO:
  format: '<b>{point.name}</b>: {point.percentage:.1f} %',

Try this code. It works for me:

  'labelFormatter':function () { 
       var total = 0, percentage; 
       $.each(this.series.data, function() { 
          total+=this.y; 
       }); 

       percentage=((this.y/total)*100).toFixed(1); 
       return this.name+' '+percentage+'%'; 
    }
