 plotOptions:{ pie: { ...., size: '75%' } }, series: [{ center: [ '25%', '50%' ], data: [ [ 'Nintendo', 54030288 ], [ 'Electronic Arts', 31367739 ], .... ] }, { center: [ '75%', '50%' ], dataLabels: { formatter: function() { var str = this.point.name + ': ' + Highcharts.numberFormat(this.percentage, ...
