1、图表报表简介

​ 在大数据时代，人们需要对大量的数据进行分析，帮助用户或公司领导更直观的察觉差异，做出判断，减少时间成本，而在web项目中除了表格显示数据外，还可以通过图表来表现数据，这种图表形式表现数据使人看的清楚明白且更加直观。对于web项目展示图形报表使用最多的技术就是基于js的前端报表框架，目前前端市场使用最多的图形报表框架有：JfreeChart、ECharts、Highcharts、FusionCharts、amCharts等。

2、JFreechart

2.1 简介

JFreeChart是JAVA平台上的一个开放的图表绘制类库。它完全使用JAVA语言编写，可生成饼图（pie charts）、柱状图（bar charts）、散点图（scatter plots）、时序图（time series）、甘特图（Gantt charts）等等多种图表，并且可以产生PNG和JPEG格式的输出，还可以与PDF或EXCEL关联。

</div>
</body>
<script>new Vue({el:"#app",data:{},methods: {columnCharts() {},lineCharts(){},pieCharts(){}}
});
</script>
</html>

3.5 统计各部门人数（柱状图）

第一步：准备sql语句：用户表和部门表关联查询，根据部门名称分组统计

select dept_name deptName,count(u.id) num from tb_dept d LEFT JOIN tb_user u on  d.id=u.dept_id GROUP BY dept_name

第二步：后台代码

1、创建一个新的StatController

package com.itheima.controller;import com.itheima.service.StatService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
import java.util.Map;@RestController
@RequestMapping("/stat")
public class StatController {@Autowiredprivate StatService statService;@GetMapping(value = "/columnCharts",name = "统计各部门人数，柱状图")public List<Map> columnCharts(){return  statService.columnCharts();}
}

2、创建StatService

package com.itheima.service;import com.itheima.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;
import java.util.Map;@Service
public class StatService {@Autowiredprivate UserMapper userMapper;public List<Map> columnCharts() {return userMapper.columnCharts();}
}

3、UserMapper定义方法

@Select(value = "select dept_name deptName,count(u.id) num from tb_dept d LEFT JOIN tb_user u on  d.id=u.dept_id GROUP BY dept_name")List<Map> columnCharts();

第三步：完成js方法

在highcharts_index.html页面中参考highcharts官网上的柱状图完成以下代码

https://www.highcharts.com.cn/demo/highcharts/column-basic

 methods: {columnCharts() {axios.get("/stat/columnCharts").then(res => {let datas = res.data;let titles=[];  //x轴上显示的数据let values=[]; //y轴上显示的数据for (let i = 0; i < datas.length; i++) {titles[i] = datas[i].deptName;values[i] = datas[i].num;}Highcharts.chart('container', {chart: {type: 'column'},title: {text: '各部门人数'},xAxis: {categories:titles,crosshair: true},yAxis: {min: 0,title: {text: '人数'}},tooltip: {// head + 每个 point + footer 拼接成完整的 tableheaderFormat: '<span style="font-size:10px">{point.key}</span><table>',pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +'<td style="padding:0"><b>{point.y:.1f} </b></td></tr>',footerFormat: '</table>',shared: true,useHTML: true},plotOptions: {column: {borderWidth: 0}},series: [{name: '各部门人数',data: values}]});})},pieCharts(){},lineCharts(){}}

最后效果：

3.6 月份入职人数统计（折线图）

第一步：准备SQL语句

一年12个月，想知道什么月份入职的人员最后

select m.name,IFNULL(t.num,0) num from tb_month m LEFT JOIN (
select DATE_FORMAT(hire_date,'%m') months ,count(id) num from tb_user GROUP BY DATE_FORMAT(hire_date,'%m')
) t ON m.name=t.months

第二步：完成后台代码

1、StatController添加方法

@GetMapping(value = "/lineCharts",name = "月份入职人数统计，折线图")
public List<Map> lineCharts(){return  statService.lineCharts();
}

2、StatService添加方法

public List<Map> lineCharts() {return userMapper.lineCharts();
}

3、UserMapper添加方法

@Select("select m.name,IFNULL(t.num,0) num from tb_month m LEFT JOIN ( " +"select DATE_FORMAT(hire_date,'%m') months ,count(id) num from tb_user GROUP BY DATE_FORMAT(hire_date,'%m') " +") t ON m.name=t.months")
List<Map> lineCharts();

第三步：完成js代码

在highcharts_index.html页面中参考highcharts官网上的柱状图完成以下代码

https://www.highcharts.com.cn/demo/highcharts/line-basic

lineCharts(){axios.get("/stat/lineCharts").then(res=>{let datas = res.data;let values=[]; //y轴上显示的数据for (let i = 0; i < datas.length; i++) {values[i] = datas[i].num;}var chart = Highcharts.chart('container', {title: {text: '月份入职人数统计'},yAxis: {title: {text: '入职人数'}},legend: {layout: 'vertical',align: 'right',verticalAlign: 'middle'},plotOptions: {series: {label: {connectorAllowed: false},pointStart: 2010}},series: [{name: '入职人数',data: values}],responsive: {rules: [{condition: {maxWidth: 500},chartOptions: {legend: {layout: 'horizontal',align: 'center',verticalAlign: 'bottom'}}}]}});})
}

效果：

3.7 员工地方来源统计（可下钻的饼状图）

统计公司员工的来源

第一步：环境准备

什么是下钻的效果

https://www.highcharts.com.cn/demo/highcharts/column-drilldown

https://www.highcharts.com.cn/demo/highcharts/pie-drilldown

如果想要下钻的效果，需要在多引入一个js，从下载的压缩包中找到后放到项目中，并且在html中引入

<script src="js/drilldown.js"></script>

第二步：后台方法准备数据

1、StatController代码添加方法

@GetMapping(value = "/pieCharts",name = "公司员工地方来源，包括省、市")
public List<Map> pieCharts(){return  statService.pieCharts();
}

3、StatService中添加方法

这个方法直接返回js上需要的所有数据

[{id:“河北省”,“drilldown”:“河北省”,“name”:“河北省”,“y”:10,“data”:[{“name”:“石家庄”,“y”:4},{“name”:“唐山”,“y”:3},{“name”:“保定”,“y”:3}]}]

public List<Map> pieCharts() {List<Map> resultMapList = new ArrayList();
//        最终想要的数据格式：[{id:"河北省","drilldown":"河北省","name":"河北省","y":10,"data":[{"name":"石家庄","y":4},{"name":"唐山","y":3},{"name":"保定","y":3}]}]List<User> userList = userMapper.selectAll(); //查询所有员工数据
//        根据省份分组Map<String, List<User>> provinceMap = userList.stream().collect(Collectors.groupingBy(User::getProvince));for (String provinceName : provinceMap.keySet()) {int provinceSize = 0;Map resultMap = new HashMap();resultMap.put("id",provinceName);resultMap.put("drilldown",provinceName);resultMap.put("name",provinceName);
//            再根据城市分组Map<String, List<User>> cityMap = provinceMap.get(provinceName).stream().collect(Collectors.groupingBy(User::getCity));List<Map> dataMapList = new ArrayList<>();for (String cityName : cityMap.keySet()) {Map dataMap = new HashMap();dataMap.put("name",cityName);int citySize = cityMap.get(cityName).size();dataMap.put("y",citySize);dataMapList.add(dataMap);provinceSize+=citySize;}resultMap.put("y",provinceSize);resultMap.put("data",dataMapList);resultMapList.add(resultMap);}return resultMapList;}

第三步：完成js代码

 pieCharts(){axios.get("/stat/pieCharts").then(res=>{let datas = res.data;Highcharts.chart('container', {chart: {type: 'column'},title: {text: '公司原因地方来源'},xAxis: {type: 'category'},yAxis: {title: {text: '人数'}},legend: {enabled: false},plotOptions: {series: {borderWidth: 0,dataLabels: {enabled: true,format: '{point.y}'}}},tooltip: {headerFormat: '<span style="font-size:11px">{series.name}</span><br>',pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y}</b><br/>'},series: [{name: '省份',colorByPoint: true,data: datas}],drilldown: {series: datas}});})}

效果：

点击河北省

4、Echarts

4.2 下载安装

1、下载js

https://github.com/apache/incubator-echarts/tree/4.7.0

或 从 npm 安装 (前提是电脑上有node环境)

npm install echarts

2、把下载好的js放入到项目中

4.3 入门案例

第一步 导入js依赖

<!DOCTYPE html>
<html>
<head><meta charset="utf-8"><!-- 引入 ECharts 文件 --><script src="js/echarts.min.js"></script>
</head>
</html>

4.3.2 配置dom容器

在绘图前我们需要为 ECharts 准备一个具备高宽的 DOM 容器。

<body><!-- 为 ECharts 准备一个具备大小（宽高）的 DOM --><div id="main" style="width: 600px;height:400px;"></div>
</body>

4.3.3 初始化图形

然后就可以通过 echarts.init 方法初始化一个 echarts 实例并通过 setOption 方法生成一个简单的柱状图，下面是完整代码。

<!DOCTYPE html>
<html>
<head><meta charset="utf-8"><title>ECharts</title><!-- 引入 echarts.js --><script src="echarts.min.js"></script>
</head>
<body><!-- 为ECharts准备一个具备大小（宽高）的Dom --><div id="main" style="width: 600px;height:400px;"></div><script type="text/javascript">// 基于准备好的dom，初始化echarts实例var myChart = echarts.init(document.getElementById('main'));// 指定图表的配置项和数据var option = {title: {text: 'ECharts 入门示例'},tooltip: {},legend: {data:['销量']},xAxis: {data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]},yAxis: {},series: [{name: '销量',type: 'bar',data: [5, 20, 36, 10, 10, 20]}]};// 使用刚指定的配置项和数据显示图表。myChart.setOption(option);</script>
</body>
</html>

效果：

4.4 准备页面

在static下新建一个页面echarts_index.html 内容如下

<!DOCTYPE html>
<html>
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0,user-scalable=no,minimal-ui" /><title>echarts图表报表</title><link rel="stylesheet" href="css/charts_demo.css"><script src="js/vuejs-2.5.16.js"></script><script src="js/axios-0.18.0.js"></script><script src="js/echarts.min.js"></script></head>
<body>
<div id="app" class="my-box"><div class="my-box-left"><button @click="columnCharts">统计各部门人数</button> <br/> <br/><button @click="lineCharts">月份入职人数统计</button> <br/> <br/><button @click="pieCharts">员工地方来源统计</button> <br/> <br/><button @click="mapCharts">员工地方来源统计(地图)</button> <br/> <br/></div><div class="my-box-right"><div id="container" style="height:450px;"></div></div>
</div>
</body>
<script>new Vue({el:"#app",data:{},methods: {columnCharts() {},lineCharts(){},pieCharts(){},mapCharts(){}}});
</script>
</html>

4.5 统计各部门人数（柱状图）

官网参考 https://echarts.apache.org/examples/zh/editor.html?c=bar-simple

可以直接使用3.5小结highcharts的后台方法

修改echarts_index.html中的js方法

columnCharts() {axios.get("/stat/columnCharts").then(res=>{let datas = res.data;let titles=[];  //x轴上显示的数据let values=[]; //y轴上显示的数据for (let i = 0; i < datas.length; i++) {titles[i] = datas[i].deptName;values[i] = datas[i].num;}var myChart = echarts.init(document.getElementById('container'));// 指定图表的配置项和数据var option = {title: {text: '各部门人数'},tooltip: {},legend: {data:['人数']},xAxis: {data: titles},yAxis: {},series: [{name: '人数',type: 'bar',data: values}]};// 使用刚指定的配置项和数据显示图表。myChart.clear();myChart.setOption(option);})
}

效果：

4.6 月份入职人数统计（折线图）

官网参考 https://echarts.apache.org/examples/zh/editor.html?c=line-simple

可以直接使用3.6小结highcharts的后台方法

修改echarts_index.html中的js方法

lineCharts(){axios.get("/stat/lineCharts").then(res=>{let datas = res.data;let titles=[];  //x轴上显示的数据let values=[]; //y轴上显示的数据for (let i = 0; i < datas.length; i++) {titles[i] = datas[i].name;values[i] = datas[i].num;}var myChart = echarts.init(document.getElementById('container'));option = {xAxis: {type: 'category',data: titles},yAxis: {type: 'value'},series: [{data: values,type: 'line'}]};// 使用刚指定的配置项和数据显示图表。myChart.clear();myChart.setOption(option);})
}

4.7 员工地方来源统计（饼图）

Echarts没有提供下钻的效果，但是有一个和下钻类似的效果

官网参考 https://echarts.apache.org/examples/zh/editor.html?c=pie-nest

安装官网上给的参考数据，会发现需要用到三种数据：省份集合、城市集合、城市名称集合

第一步：根据需求后台提供数据

1、StatController新添加一个方法

@GetMapping(value = "/pieECharts",name = "公司员工地方来源，包括省、市")
public Map  pieECharts(){return  statService.pieECharts();
}

2、StatService处理数据

public  Map pieECharts() {Map resultMap = new HashMap();//        最终想要的数据格式：{province:[{name:,value:}],city:[]}Example example = new Example(User.class);example.setOrderByClause("province , city");List<User> userList = userMapper.selectByExample(example); //查询所有员工数据//        根据省份分组List<Map> provinceMapList = new ArrayList<>();//        注意分组时得排序，不然数据会乱Map<String, List<User>> provinceMap = userList.stream().collect(Collectors.groupingBy(User::getProvince,LinkedHashMap::new,Collectors.toList()));for (String provinceName : provinceMap.keySet()) {Map map = new HashMap();map.put("name",provinceName);map.put("value",provinceMap.get(provinceName).size());provinceMapList.add(map);}List<Map> cityMapList = new ArrayList<>();//        注意分组时得排序，不然数据会乱Map<String, List<User>> cityMap = userList.stream().collect(Collectors.groupingBy(User::getCity, LinkedHashMap::new,Collectors.toList()));for (String cityName : cityMap.keySet()) {Map map = new HashMap();map.put("name",cityName);map.put("value",cityMap.get(cityName).size());cityMapList.add(map);}resultMap.put("province",provinceMapList);resultMap.put("city",cityMapList);return resultMap;
}

第二步：完成JS代码

pieCharts(){axios.get("/stat/pieECharts").then(res=>{let datas = res.data;// 需要三种数据：都可以从datas中获取//  1、省份数据 [{name:"河北省",value:10}]// 2、城市数据 [{name:"石家庄",value:3}]// 3、城市的名称let provinceData =  datas.province;let cityData = datas.city;let cityNames = [];for (let i = 0; i < cityData.length; i++) {cityNames[i] = cityData[i].name;}var myChart = echarts.init(document.getElementById('container'));option = {tooltip: {trigger: 'item',formatter: '{a} <br/>{b}: {c} ({d}%)'},legend: {orient: 'vertical',left: 10,data: cityNames},series: [{name: '员工来源',type: 'pie',selectedMode: 'single',radius: [0, '30%'],label: {position: 'inner'},labelLine: {show: false},data: provinceData},{name: '员工来源',type: 'pie',radius: ['40%', '55%'],label: {formatter: '{a|{a}}{abg|}\n{hr|}\n  {b|{b}：}{c}  {per|{d}%}  ',backgroundColor: '#eee',borderColor: '#aaa',borderWidth: 1,borderRadius: 4,// shadowBlur:3,// shadowOffsetX: 2,// shadowOffsetY: 2,// shadowColor: '#999',// padding: [0, 7],rich: {a: {color: '#999',lineHeight: 22,align: 'center'},// abg: {//     backgroundColor: '#333',//     width: '100%',//     align: 'right',//     height: 22,//     borderRadius: [4, 4, 0, 0]// },hr: {borderColor: '#aaa',width: '100%',borderWidth: 0.5,height: 0},b: {fontSize: 16,lineHeight: 33},per: {color: '#eee',backgroundColor: '#334455',padding: [2, 4],borderRadius: 2}}},data: cityData}]};// 使用刚指定的配置项和数据显示图表。myChart.clear();myChart.setOption(option);})
}
