以下是echarts代码
 
 
 <script type="text/javascript">
  	var array_name = "<%=st_name.toString()%>";
    var array_value ="<%=st_good.toString()%>";
    
        // 路径配置

            }
        });
        
        // 使用
        require(
            [
                'echarts','echarts/chart/bar',// 使用柱状图就加载bar模块，按需加载
