使用方法

public String getPipChartXml(List ls,String caption) {

        try {

            String clickUrl = "";

            PipChartHelper helper=new PipChartHelper();

            helper.setCaption(caption);

            helper.setClickURL(clickUrl);

            for(int i = 0 ; i < ls.size() ; i++){

                Object[] str = (Object[]) ls.get(i);

                String a = (String)str[0];//部门

                Double b = (Double)str[1];//水费

                helper.addDataItem(a, b);

            }

            String xmlData = helper.createChartXmlData();

            return xmlData;

        } catch (Exception e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

            return null;

        }

    }
