        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;
        }
