?2、xml配置：

<!-- 单个学生成绩分析 -->
		<action name="studentScoreAnalyse" class="jxq.xxt.scoremanage.action.StudentScoreAnalyseAction">
			<result name="input" type="freemarker">/scoremanage/studentScoreAnalyse_index.ftl</result>
			<result name="success" type="json"></result>
		</action>

?3、页面：

$(document).ready(function(){
	
	<!--当第一次进来页面  显示总分-->
	if(${flag}==1){
		var chart;  
		var chartData = [	
							{
								category:'最高分',
							 	score:'${maxScore}',
							 	color: "#FF0F00"
							},
							{
								category:'最低分',
								score:'${minScore}',
								color: "#88003B"
							},
							{
								category:'平均分',
								score:'${averageScore}',
								color : "#FF4D34"
							},
							{
								category:'${userName}分数',
								score:'${score}',
								color : "#0081AC"
							}
						];
						
		AmCharts.ready(function(){
				
                chart = new AmCharts.AmSerialChart();
                chart.dataProvider = chartData;
                chart.categoryField = "category";
                <!--the following two lines makes chart 3D--> 
                chart.depth3D = 20;
                chart.angle = 30;
                <!--字体大小-->
				chart.fontSize = 13;
				chart.startDuration = 1;
				chart.columnWidth = 0.4;
				
                <!--category-->
                var categoryAxis = chart.categoryAxis;
                <!--横轴文字角度 0为水平显示  90为竖直显示  默认90-->
                categoryAxis.labelRotation = 0;
