前言:我是自己最近写项目用到的,我做个整理;
一. 基本使用
1.具有大小(宽高)的div ,id唯一;
例如:
<div id="crewEchart"></div>2.在项目中引入:
import * as echarts from "echarts";3.写一个关于他的方法,在mounted的时候调用:
mounted() {
this.setEcharts()//你自己起一个功能相关的名字就行;
}4.在methods中写他的配置项:
methods:{
setWarnEcharts(){},
}二.配置项
以折线图为例:
1.图:
2.代码:
methods:{
setWarnEcharts(){
let xLabel =['9:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00']
let online = ["180", "203", "198", "190", "198", "201", "190", "198", "190"]
let sum = ["200", "210", "215", "204", "210", "209", "210", "215", "204",]

}三.单项介绍
1.以上图为例,简单介绍几个修改echarts的方法
主要是通过修改option来调整echarts图
1.修改标题:
title: {
text: '设备数量(单位:台)',//修改文字内容
top: 10,//文字位置
right: '4%',
bottom: '2%',
textStyle: {//文字样式
color: '#0099FF',//文字颜色
fontSize: 12,//文字大小
fontFamily: 'Microsoft YaHei'//文字字体
}
},2.grid网格
grid: {//这个是调整echarts图片整体的位置
top: 50,//距离上面多少
left: '6%',//左边
right: '5%',//右边
bottom: '8%',//下面
containLabel: true,//我不知道这个
},3.tooltip提示信息
tooltip: {//提示信息,当鼠标放在图表上展示的内容,红框选中部分
trigger: 'axis',
backgroundColor:'red',
axisPointer: {
lineStyle: {//线的样式,绿框选中部分
type: 'solid',
width: 3,
color: {
type: 'linear',
x: 0,
y: 0,
x2: 0,
y2: 1,
colorStops: [{
offset: 0,
color: 'rgba(126,199,255,0)' // 0% 处的颜色
}, {
offset: 0.5,
color: 'rgba(126,199,255,1)' // 100% 处的颜色
}, {
offset: 1,
color: 'rgba(126,199,255,0)' // 100% 处的颜色
}],
global: false // 缺省为 false
}
},
},
formatter: (p) => {//这个可以用来自定义
let dom = `<div style="width: 100px;
height: 50px;;color:#fff;position: relative;">
<svg style="position: absolute;top: 50%;

return dom
}
},4.x轴设置: xAxis
xAxis: [{
type: 'category',
boundaryGap: false,
axisLine: { //坐标轴轴线相关设置。数学上的x轴
lineStyle: {
color: 'red',//x轴线的颜色
},
},
axisLabel: { //坐标轴刻度标签的相关设置
textStyle: {//x轴文字的样式设置
show: true,
color: 'red',//x轴文字的颜色
padding: 16,
fontSize: 14
},
formatter: function(data) {
return data
}
},
splitLine: {
show: true,
lineStyle: {
color: 'red',//竖线颜色
},
},
axisTick: {
show: true,
inside: true
},
data: xLabel,//x轴数据
}],5.y轴设置:yAxis
yAxis: [{
name: '数量',//y轴名字
nameTextStyle: {//y轴文字样式设置
color: "#7ec7ff",
fontSize: 16,
padding: 10
},
min: 10,//y轴的最小值
splitLine: {
show: false,
lineStyle: {
color: '#2AF4F7'
},
},
axisLine: {//y轴线的颜色
show: true,
lineStyle: {
color: "#0099FF"
},
},
axisLabel: {
show: true,
textStyle: {
color: 'green',//y轴文字的颜色
padding: 16
},
formatter: function(value) {//这里可以自定义,对y轴数据进行处理
if (value === 0) {
return value
}
return value
}
},
axisTick: {
show: false,
},
}],6.series 主要是调整他,折线图 饼图 等等,上面设置了横纵坐标,接下来设置内容...
series: [{//一个{}表示第一条数据
