第一步

新建页面line.html,引入HighCharts核心js文件

<script type="text/javascript" src="../../js/Highcharts/highcharts.js"></script>

第二步

插入折线图容器   <div  id="container"></div>

第三步

编写脚本从服务器端请求数据

 

 

makeColumnChart("DBT_GLWMD","#container1");

function makeColumnChart(chartName,container) {

        $(container).show();

        $(container).empty();

        var request;

        index = layer.load(1, {

           shade : [ 0.1, '#fff' ] //0.1透明度的白色背景

        });

        request = $

              .ajax({

                 url : "../../subjectInfo",

                 type : "POST",

                 contentType : "application/x-www-form-urlencoded; charset=UTF-8",

                 data : {

                    operType : "chart_Column",

                    startYear : $.trim($("#startYear").val()),

                    //endYear : $.trim($("#endYear").val()),

                    cName : chartName

                 },

                 dataType : "html"

              });

        if(chartName=="DBT_GLWMD"){

           titleText = $("#startYear").val() + '年公路网密度对比图';

        }

        if(chartName=="DBT_PTGX"){

           titleText = $("#startYear").val() + '年普通干线二级及以上比例对比图';

        }

        if(chartName=="DBT_NCGL"){

           titleText = $("#startYear").val() + '年农村公路等级及以上比例对比图';

        }

       

        request.done(function(msg) {

           layer.close(index);

           if (msg != "") {

              var jdata = strToJson(msg);

              if(chartName=="DBT_GLWMD"){

                 creatColumn(jdata, titleText, container);

              }

              if(chartName=="DBT_PTGX"){

                 creatColumnWithPer(jdata, titleText, container);

              }

              if(chartName=="DBT_NCGL"){

                 creatColumnWithPer(jdata, titleText, container);

              }

           }

        });

      }

 

      function strToJson(str) {//字符串转换为json

        var json = eval('(' + str + ')');

        return json;

      }

第四步

服务器端获取数据

result="[{name: '全省',y:"+sProvince+" }, {name: '贫困地区',y:"+sPK+" }, {name: '"+sCountyName+"',y:"+sCounty+"}]";

 

request.setCharacterEncoding("utf-8");

response.setContentType("text/html;charset=UTF-8");

PrintWriter out = response.getWriter();

out.write(result);

第五步 编写脚本生成柱状图

function creatColumn(data,titleStr,container) {

        $(container)

        .highcharts(

              {

                lang : {

                    printChart : "打印图表",

                    downloadJPEG : "下载JPEG 图片",

                    downloadPDF : "下载PDF文档",

                    downloadPNG : "下载PNG 图片",

                    downloadSVG : "下载SVG 矢量图",

                    exportButtonTitle : "导出图片"

                 },

                 chart: {

                       type: 'column'

                   },

                   title: {

                       text: titleStr

                   },

                   credits : {

                    enabled : false

                 },

                   xAxis: {

                       type: 'category'

                   },

                   yAxis: {

                       title: {

                           text: ''

                       }

                   },

                   legend: {

                       enabled: false

                   },

                   plotOptions: {

                       series: {

                           borderWidth: 0,

                           dataLabels: {

                               enabled: true,

                               format: '{point.y:.0f}'

                           }

                       }

                   },

                   tooltip: {

                       headerFormat: '<span style="font-size:11px">{series.name}</span><br>',

                       pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.0f}</b> of total<br/>'

                   },

                   series: [{

                       name: '对比图',

                       colorByPoint: true,

                       data: eval(data)

                   }]

              });

      }

 

function creatColumnWithPer(data,titleStr,container) {

        $(container)

        .highcharts(

              {

                 lang : {

                    printChart : "打印图表",

                    downloadJPEG : "下载JPEG 图片",

                    downloadPDF : "下载PDF文档",

                    downloadPNG : "下载PNG 图片",

                    downloadSVG : "下载SVG 矢量图",

                    exportButtonTitle : "导出图片"

                 },

                 chart: {

                       type: 'column'

                   },

                   title: {

                       text: titleStr

                   },

                   credits : {

                    enabled : false

                 },

                   xAxis: {

                       type: 'category'

                   },

                   yAxis: {

                       title: {

                           text: ''

                       },

                       labels: {//y轴刻度文字标签 

                              formatter: function () { 

                                  return this.value + '%';//y轴加上% 

                              } 

                          }, 

                   },

                   legend: {

                       enabled: false

                   },

                   plotOptions: {

                        series: {

                           borderWidth: 0,

                           dataLabels: {

                               enabled: true,

                               formatter : function() {

                                 return this.y + "%";  //返回百分比和个数

                             }

                           }

                       }

                   },

                   tooltip: {

                       headerFormat: '<span style="font-size:11px">{series.name}</span><br>',

                       pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.0f}%</b> of total<br/>'

                   },

                   series: [{

                       name: '对比图',

                       colorByPoint: true,

                       data: eval(data)

                   }]

              });

      }
