Highcharts将数据以图表的形式展现

1、首先将Highcharts插件所需的js跟css样式文件引入项目中，下载地址为：Highcharts.rar

2、在前台页面中添加一个存放图表的容器

<div id="container" style="min-width: 400px; height: 500px; margin: 0 auto"></div>

3、在后台拼接json数据

 @Action("ycccBarGramData")
    public void ycccBarGramData() {
        try {
            String nyStr = FormatDate.getNyStr(tjksny, tjjsny);
            List<Map<String, Object>> resultList = this.ycccService.getYcccList(nyStr, jgdm);
            if (resultList != null && resultList.size() > 0) {
                String yValue = "";
                String yData = "";
                Map<String, Object> data = resultList.get(0);
                String[] params = new String[]{"YCZS", "WCLS", "YFKWCLS", "RQS", "JDWCLS", "YJDBLS", "YJDQSHQRS", "ZS"};
                for (int i = 0; i < params.length; i++) {
                    yData += data.get(params[i]) + ",";
                }
                yData = yData.substring(0, yData.length() - 1);
                yValue += "{type:'column',name:'" + data.get("JGMC") + "',data:[" + yData + "]}";
                StringBuffer arrJson = new StringBuffer("{");
                arrJson.append("\"iSucc\":true");
                arrJson.append(",\"title\":\"异常查处分布图(" + tjksny + "至" + tjjsny + ")\"");
                arrJson.append(",\"subTitle\":\"(" + tjksny + "至" + tjjsny + ")\"");
                arrJson.append(",\"yTitle\":\"异常查处数\"");
                arrJson.append(",\"xValue\":\"['异常总数','未处理数','已反馈未处理数','日清数','监督未处理数','已监督办理数','已监督且审核确认数','总数']\"");
                arrJson.append(",\"yValue\":\"[" + yValue + "]\"");
                arrJson.append("}");
                this.renderHtml(arrJson.toString());
            } else {
                this.renderHtml("{\"iSucc\":false,\"noData\":true}");
            }
        } catch (Exception e) {
            this.renderHtml("{\"iSucc\":false}");
            e.printStackTrace();
        }
    }

4、在前台页面中接受后台传过去的json数据

$(function () {
        var tjksny = "<#if tjksny??>${tjksny}</#if>";
        var tjjsny = "<#if tjjsny??>${tjjsny}</#if>";
        var jgdm = "<#if jgdm??>${jgdm}</#if>";
        $.post(
                "${base}/fxyp/ycccBarGramData",
                {
                    "tjksny":tjksny,
                    "tjjsny":tjjsny,
                    "jgdm":jgdm
                },
                function (data) {
                    var json = eval("(" + data + ")");
                    initBarDate(json.title, json.subTitle, json.yTitle, json.xValue, json.yValue);
                });
    });

    function initBarDate(title, subTitle, yTitle, xValue, yValue) {
        //获取图标系统所有颜色
        var colors = Highcharts.getOptions().colors;
        //初始化图标
        chart = new Highcharts.Chart({
            chart:{
                renderTo:'container', //返回id为container容器
                defaultSeriesType:'column', //返回样式
                marginTop:105, //图标距离上方距离
                marginRight:15,
                type:'column'
            },
            title:{
                text:'<span style="font-size:13px;">' + title + '</span>'               //标题
            },
            subtitle:{                         //子标题
                text:'<span style="color:red">' + subTitle + '</span>',
                floating:true
            },
            xAxis:{                          //x轴数据构造
                categories:eval('(' + xValue + ')'),
                title:{
                    text:'异常类型'
                },
                labels:{
                    rotation:-45,
                    align:'right',
                    style:{
                        fontSize:'13px',
                        fontFamily:'Verdana, sans-serif'
                    }
                }
            },
            yAxis:{
                min:0,
                title:{
                    text:'异常数量'
                }
            },
            tooltip:{
                formatter:function () {
                    return '' +
                            this.x + ': ' + this.y;
                }
            },
            plotOptions:{
                column:{
                    pointPadding:0.2,
                    borderWidth:0,
                    dataLabels:{

                        formatter:function () {
                            return this.y;
                        }
                    }
                }
            },
            legend:{
                layout:'vertical', //【图例】显示的样式：水平（horizontal）/垂直（vertical）
                backgroundColor:'#FFFFFF',

            },
            credits:{
                enabled:true
            },
            exporting:{                     //导出

    }
