使用方法：

        try {
            String clickUrl = "";
            StackedColumnChartHelper helper=new StackedColumnChartHelper();
            helper.setCaption(caption);
            helper.setClickURL(clickUrl);
            StackedColumnChartHelper.DateSet dataSet1=helper.createDataSet();
            StackedColumnChartHelper.DateSet dataSet2=helper.createDataSet();
            dataSet1.setSeriesName("水费");
            dataSet2.setSeriesName("电费");
            helper.addDateSet(dataSet1);
            helper.addDateSet(dataSet2);
            for(WaterAndPowerVo waterAndPowerVo:ls){
                helper.addCategory(waterAndPowerVo.getMonth());
                dataSet1.addSetItem(waterAndPowerVo.getWaterPrice(), "");
                dataSet2.addSetItem(waterAndPowerVo.getPowerPrice(), "");
            }
            String xmlData = helper.createChartXmlData();
            return xmlData;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
