1、vue 安裝 echart 庫
npm install echarts --save
2、vue代碼
引入
let echarts = require("echarts/lib/echarts");
require("echarts/lib/chart/line");
// 以下的組件按需引入
require("echarts/lib/component/tooltip"); // tooltip組件
require("echarts/lib/component/title"); // title組件
require("echarts/lib/component/legend"); // legend組件
html 代碼
<div id="myChart" style="width: 725px;height: 300px"></div>
js代碼
mounted(){
this.drawLine();
},
methods: {
drawLine(){
// 基於准備好的dom,初始化echarts實例
let myChart = echarts.init(document.getElementById('myChart'));
// 繪制圖表
myChart.setOption({
title: {
text: '',
subtext: ''
},
tooltip: {
trigger: 'axis'
},
color:['#78d528','#fa7371'],
legend: {
data:[
{
name:"舒張壓",
textStyle: {
color:'#78d528'
}
},{
name: "收縮壓",
textStyle: {
color:'#fa7371'
}
}
]
},
toolbox: {
show: true,
feature: {
dataZoom: {
yAxisIndex: 'none'
},
dataView: {readOnly: false},
magicType: {type: ['line', 'bar']},
restore: {},
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: false,
data: [
'07:00',
'08:00',
'09:00',
'10:00',
'11:00',
'12:00',
'13:00',
'14:00',
'15:00',
'16:00',
'17:00',
]
},
yAxis: {
type: 'value',
splitLine: {
show: true,
lineStyle:{
type:'dashed'
}
},
axisLabel: {
formatter: '{value}'
}
},
series: [
{
name:'舒張壓',
type:'line',
stack: '總量',
lineStyle:{
normal:{
color:'#78d528'
}
},
data:[
120,
132,
101,
134,
12,
45,
56,
34,
76,
134,
90,
230,
210
]
},
{
name:'收縮壓',
type:'line',
lineStyle:{
normal:{
color:'#fa7371'
}
},
stack: '總量',
data:[
55,
32,
11,
32,
12,
45,
56,
34,
76,
134,
90,
43,
54
]
},
]
});
},
}
整體效果:

3、重點來了-定義樣式
虛線:

yAxis: {
type: 'value',
/********定義樣式開始********/
splitLine: {
show: true,
lineStyle:{
type:'dashed' //定義樣式=虛線
}
},
/********結束********/
axisLabel: {
formatter: '{value}'
}
},
4、改變legend的樣式

代碼:
1 color:['#78d528','#fa7371'], //分別定義第一個legend和第二個legend的icon顏色 2 legend: { 3 data:[ 4 { 5 name:"舒張壓", 6 textStyle: { 7 color:'#78d528' //定義 legend 的字體顏色 8 } 9 },{ 10 name: "收縮壓", 11 textStyle: { 12 color:'#fa7371' //定義 legend 的字體顏色 13 } 14 } 15 ] 16 },
5、定義x軸線條的顏色

series: [ { name:'舒張壓', type:'line', stack: '總量', lineStyle:{ normal:{ color:'#78d528' //線條顏色 } },
//數據 data:[ 120, 132, 101, 134, 12, 45, 56, 34, 76, 134, 90, 230, 210 ] }, { name:'收縮壓', type:'line', lineStyle:{ normal:{ color:'#fa7371'//線條顏色 } }, stack: '總量',
//數據 data:[ 55, 32, 11, 32, 12, 45, 56, 34, 76, 134, 90, 43, 54 ] },
