overlapping labels in piechart

relevant bits of code:

fetching data:

get_data_from_pos_basket_for_reporting getreportpaymentpaidunpaidnoclass=new get_data_from_pos_basket_for_reporting();         getreportpaymentpaidunpaidnoclass.getreportpaymentpaidunpaidno(fromdate, untildate);       double amountpaid,amountunpaid;       int totalpaid,totalunpaid;       amountpaid=getreportpaymentpaidunpaidnoclass.getamountpaid();       amountunpaid= getreportpaymentpaidunpaidnoclass.getamountunpaid();       totalpaid=getreportpaymentpaidunpaidnoclass.gettotalpaid();       totalunpaid=getreportpaymentpaidunpaidnoclass.gettotalunpaid();       double totalamountpaidunpaid=amountpaid+paymentsystem+amountunpaid;       double totalnopaidunpaid=totalpaid+totalunpaid;      // decimalformat df = new decimalformat("0.00");        double percentagepaidamount=((amountpaid/totalamountpaidunpaid)*100);       double percentageunpaidamount=((amountunpaid/totalamountpaidunpaid)*100);       double percentagepaidtotal=((totalpaid/totalnopaidunpaid)*100);       double percentageunpaidtotal=((totalunpaid/totalnopaidunpaid)*100);

setting piechart:

observablelist<piechart.data> piechartdata3 =                 fxcollections.observablearraylist(                 new piechart.data("paid\n"+(df.format(percentagepaidamount))+"%", amountpaid),                 new piechart.data("unpaid\n"+(df.format(percentageunpaidamount))+"%", amountunpaid));           piechart chart3 = new piechart(piechartdata3);            chart3.getstyleclass().add("chart-legend");                chart3.settitle("payment details[total amount]");         vbox vboxpie3= new vbox();         vboxpie3.getchildren().addall(chart3);

please suggest solution such labels don't overlap each other.
