第一步: 先安装echarts

npm install echarts --save

第二步:  在js中导入echarts

import * as echarts from "echarts";

第三步: 写出HTML样式,CSS样式

.echarts {

margin: auto;

border-radius: 8px;

margin-top: 20px;

width: 97%;

background-color: white;

height: 300px;

#echarts_con {

width: 100%;

height: 100%;

}

}

第四步: 在js中绑定HTML

const echarts_con = echarts.init(document.getElementById("echarts_con"));

第五步: 图表样式绘制

echarts_con.setOption({

title: {

text: "近30天订单数量",

left: 10,

top: 10,

textStyle: {

//主标题文字样式

color: "#505050", //字体颜色

fontSize: 15, //字体大小

// fontStyle:'italic',//斜体

fontWeight: 500 //加粗

}

},

grid: {

left: "5%",

right: "10%",

top: "20%",

bottom: "15%",

containLabel: true

},

tooltip: {

show: true,

trigger: "axis"

},

xAxis: [

{

type: "category",

axisLine: {

show: true,

lineStyle: {

color: "#9a9a9a"

}

},

axisTick: {

show: true

},

axisLabel: {

},

boundaryGap: ["5%", "5%"],

type: "dashed"

}

}

}

],

series: [

{

name: "订单量",

type: "line",

stack: "总量",

symbol: "circle",

data: arr.value,

symbolSize: 6,

itemStyle: {

color: "#3a8bef",

borderColor: "#3a8bef",
