//饼图

二、折线图
EchartsController
@GetMapping("/members")
public Result members() {
List<User> list = userService.list();
//四个季度
int q1 = 0;
int q2 = 0;
int q3 = 0;
int q4 = 0;
for (User user : list) {
Date createTime = user.getCreateTime();
Quarter quarter = DateUtil.quarterEnum(createTime);
switch (quarter) {
case Q1:
q1 += 1;
break;
case Q2:
q2 += 1;
break;
case Q3:
q3 += 1;
break;
case Q4:
q4 += 1;
break;
default:
break;
}
}
return Result.success(CollUtil.newArrayList(q1, q2, q3, q4));
}Home.vue
<el-col :span="12">
<div id="main" style="width: 500px;height: 400px"></div>
</el-col>
var option = {
title: {
text: '各季度会员数量趋势图',
subtext: '趋势图',
left: 'center'
},
xAxis: {
type: 'category',
data: ["第一季度","第二季度","第三季度","第四季度"]
},
yAxis: {
type: 'value'
},
series: [
{
data: [],
type: 'line'
},
{
data: [],
type: 'bar'
}
]
};
var chartDom = document.getElementById('main');
var myChart = echarts.init(chartDom);
this.request.get("/echarts/members").then(res =>{
//填空
option.series[0].data = res.data
option.series[1].data = res.data
//数据准备完毕之后在set
myChart.setOption(option);
})
三、饼图
//饼图
var pieOption = {
title: {
text: '各季度会员数量比例图',
subtext: '比例图',
left: 'center'
},
tooltip: {
trigger: 'item'
},
legend: {
orient: 'vertical',
left: 'left'
},
series: [
{
type: 'pie',
radius: '60%',
//饼图上的文本标签
label:{
normal:{
show:true,
//标签的位置
position:'inner',
textStyle:{
fontWeight:300,
fontSize:14,
color:'#fff'
},
formatter:'{d}%'
}
},
data: [],//填空
emphasis: {
itemStyle: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
};
var pieDom = document.getElementById('pie');
var pieChart = echarts.init(pieDom);
this.request.get("/echarts/members").then(res =>{
pieOption.series[0].data = [
{name:'第一季度',value:res.data[0]},
{name:'第二季度',value:res.data[1]},
{name:'第三季度',value:res.data[2]},
{name:'第四季度',value:res.data[3]},
]
pieChart.setOption(pieOption)
})
}四、构造
