fusioncharts饼图显示的一个问题

Java code

public void SendmmSStatusCodeAnalysis() {        String cityId = this.getParameter("cityId");        String time1 = this.getParameter("startTime");        statslevel = "43200";        String startTime = "";        String endTime = "";        startTime = time1 + "000000";        endTime = time1 + "312359";        List rsltLst = null;        try {            rsltLst = terminalPerformanceService                    .getPerformanceMmsBySendstatusCode(cityId, startTime,                            endTime, statslevel);        } catch (ServiceException e) {            try {                this.getResponse().getWriter().write("查询异常");            } catch (IOException e1) {                e1.printStackTrace();            }            e.printStackTrace();        }        if (rsltLst != null && !rsltLst.isEmpty()) {            Iterator itr = rsltLst.iterator();            Document document = DocumentHelper.createDocument();            Element rootEl = document.addElement("chart");            Element el = null;            HashMap rsMap = null;            String statusCode = "";            String mmsCnt = "";            String percent = "";            while (itr.hasNext()) {                rsMap = (HashMap) itr.next();                statusCode = (String) rsMap.get("statusCode");                mmsCnt = (String) rsMap.get("mmsCnt");                percent = (String) rsMap.get("percent");                el = rootEl.addElement("set");                el.addAttribute("label", statusCode);                el.addAttribute("value", mmsCnt);            }            // rootEl.addAttribute("caption", "用户品牌占比");            Element styleEl = rootEl.addElement("styles");            el = styleEl.addElement("definition");            el = el.addElement("style");            el.addAttribute("name", "dataLabeStyle");            el.addAttribute("type", "font");            el.addAttribute("size", "12");            // el.addAttribute("font", "宋体");            el.addAttribute("color", "#009900");            el = styleEl.addElement("application");            el = el.addElement("apply");            el.addAttribute("toObject", "DataLabels");            el.addAttribute("styles", "dataLabeStyle");            // log.info("\n" + document.asXML());            try {                this.getResponse().getWriter().write(document.asXML());            } catch (IOException e) {                e.printStackTrace();            }        } else {            try {                this.getResponse().getWriter().write("没有查询到数据");            } catch (IOException e) {                e.printStackTrace();            }        }    }

这是我统计出一个饼图的JAVA代码，其中 el.addAttribute("value", mmsCnt); 就是饼图里面的值，显示的是数字。但现在要求显示百分比，但我写成el.addAttribute("value", percent); //percent就是百分比的值，这样饼图就出不来了 求高手指点下。

[解决办法]
<chart caption="Marketing Expense" showPercentValues="1" pieRadius='70'> <set label='Service' value='43500' /> <set label='Banners' value='34510'/> <set label='Print Ads' value='23420' isSliced='1'/> <set label='Others' value='11450' /></chart>
其中设置这个参数（showPercentValues="1"）就行了。不是直接给他的值一个百分数，它会自动计算的。
