Как отобразить процент с 2 десятичными знаками в PieChart?

Я использую Jasper Report 5.2 и хочу генерировать PieChart и показывать процент с 2 десятичными знаками.Как отобразить процент с 2 десятичными знаками в PieChart?

Я создаю jrxml с одним piechart, и источник данных заполняется списком типов параметров типа piechart.

jrxml является:

<?xml version="1.0" encoding="UTF-8"?>

С помощью этого кода процент отображается с одним Integer. Я хочу процент с двумя десятичными знаками. Это возможно?

да. с моим кодом отображаемый процент представляет собой одно целое число. Я хочу процент с двумя десятичными знаками ... это возможно? – Marin

Хорошо, выложили ответ о том, как вы можете использовать настройку графика, извините за первую версию ответа, я должен был быстро прочитать ваш вопрос:) –

Спасибо. ваше решение отлично работает – Marin

Это possibile если вы передаете JRChartCustomizer

Пример настройщик форматирования метки, как вам нравится

public class MyChartCustomizer implements JRChartCustomizer { 

    @Override 
    public void customize(JFreeChart jfchart, JRChart jrchart) { 
     PiePlot plot = (PiePlot) jfchart.getPlot(); 
     StandardPieSectionLabelGenerator labelGen = new StandardPieSectionLabelGenerator(
       "{1} ({2})", 
       new DecimalFormat("#,##0.00"), 
       new DecimalFormat("0.00%")); 
     plot.setLabelGenerator(labelGen); 
    } 
}

В jrxml установлен атрибут на диаграмме customizerClass

<chart customizerClass="my.package.MyChartCustomizer">

В IDE вы найдете его в свойствах: «Класс настраивателя»

Примечание: класс MyChartCustomizer потребности быть в пути к классам, когда отчет выполнен
