vue中如何使用echarts
1、安装echarts依赖
npm install echarts -S
或者使用淘宝的镜像
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install echarts -S
创建图表
首先需要全局引入
在main.js中
```bash
// 引入echarts
import echarts from 'echarts'
Vue.prototype.$echarts = echarts
```bash/2、在Echarts.vue中
<template>
<div>
<div id="myChart" style="width:700px;height:500px"></div>
</div>
</template>
<script>
export default {
data() {
return {
option: {
title: {
text: "堆叠区域图",
},
tooltip: {
trigger: "axis",
axisPointer: {
type: "cross",
label: {
backgroundColor: "#6a7985",
},
},
},
legend: {
data: ["邮件营销", "联盟广告", "视频广告", "直接访问", "搜索引擎"],
},
toolbox: {
feature: {
saveAsImage: {},
},
},
grid: {
left: "3%",
right: "4%",
bottom: "3%",
containLabel: true,
},
xAxis: [
{
type: "category",
boundaryGap: false,
data: ["周一", "周二", "周三", "周四", "周五", "周六", "周日"],
},
],
yAxis: [
{
type: "value",
},
],
series: [
{
name: "邮件营销",
type: "line",
stack: "总量",
areaStyle: {},
data: [120, 132, 101, 134, 90, 230, 210],
},
{
name: "联盟广告",
type: "line",
stack: "总量",
areaStyle: {},
data: [220, 182, 191, 234, 290, 330, 310],
},
{
name: "视频广告",
type: "line",
stack: "总量",
areaStyle: {},
data: [150, 232, 201, 154, 190, 330, 410],
},
{
name: "直接访问",
type: "line",
stack: "总量",
areaStyle: {},
data: [320, 332, 301, 334, 390, 330, 320],
},
{
name: "搜索引擎",
type: "line",
stack: "总量",
label: {
normal: {
show: true,
position: "top",
},
},
areaStyle: {},
data: [820, 932, 901, 934, 1290, 1330, 1320],
},
],
},
};
},
mounted() {
var myChart = this.$echarts.init(document.getElementById("myChart"));
myChart.setOption(this.option);
},
};
</script>
注意：我们要在mounted生命周期函数中实例化echarts对象。因为我们要确保dom元素已经挂载到页面中
这样一个简单的图表就完成了，是不是觉得很简单
