使用方法：

private String getStackedColumnChartXml(List<WaterAndPowerVo> ls,String caption){

        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;

        }

    }
