FusionCharts+Struts2+AJAX动态报表
前台画面选择不同的检索条件通过ajax传递到后台，后台检索数据库动态构建XML格式字符串返回，前台生成对应的图像。示例是一个折线图。
Jquery部分
chartsPath为图标模板swf的位置
function showSplineCharts(url) {$.post(url, null, function(result) {var myChart = new FusionCharts(chartsPath, "myChartId", "900", "600", "0", "1" );myChart.setDataXML(result);myChart.render("chartContainer");});}Action部分
