Convert pie chart to semi-circle donut

HamzaJ Please check if below script works for you:

widget.on('processresult', function(se, ev){
	ev.result.plotOptions.pie.startAngle= -90,
    ev.result.plotOptions.pie.endAngle= 90,
    ev.result.plotOptions.pie.center= ['50%', '85%'],
    ev.result.plotOptions.pie.size= '110%'
    ev.result.plotOptions.pie.innerSize= '50%'
