highcharts插件使用总结和开发中遇到的问题及解决办法

<! -- jquery的js要在引入highchart插件的js之前引入 -->

显示highchart图标的js代码
  $(function () {
    //填充数据使用,使用jquery来获取隐藏域的值
    var xAxisTimeInfo = $("#xAxisTime").val();
    var totalRecordInfo = $("#totalRecord").val();
    var totalRecordHYInfo = $("#totalRecordHY").val();
    var totalRecordLJInfo = $("#totalRecordLJ").val();

        $('#container').highcharts({
            chart: {
                type: 'spline'
            },

Dao层的代码片段,查询数据封装成map，然后把map数据放到List中，然后在把list放到map中，调用json-lib插件转换成json数据

List ltHY = findSQL(dto, sqlHY.toString(), list.toArray());
List adminSqlTotalHY = new ArrayList();

//使用的LinkedHashMap，放到map中的数据使用顺序的 Map<String ,String> totalRecordHYMap = new LinkedHashMap<String ,String>(); for (int i = 0; ltHY!=null && i < ltHY.size(); i++) { Object[] obj = (Object[]) ltHY.get(i); totalRecordHYMap.put(obj[0]!=null?String.valueOf(obj[0]):"" ,obj[1]!=null? String.valueOf(obj[1]):""); } adminSqlTotalHY.add(totalRecordHYMap); //保存到map中 Map recordInfo = new LinkedHashMap(); recordInfo.put("Record_total", adminSqlTotalList); recordInfo.put("Record_LJ", adminSqlTotalLJ); recordInfo.put("Record_HY", adminSqlTotalHY); //把map数据转化为json数据 JSONObject jsonObjectFromMap =JSONObject.fromObject(recordInfo); dto.setAddress(jsonObjectFromMap.toString());
