1、首先在项目中安装ECharts
npm install echarts
2、在main.js中进行相关的注册
import { createApp } from 'vue';
import App from './App.vue';
// echarts
import * as echarts from 'echarts'
app.config.globalProperties.$echarts = echarts
3、在组件中使用
首先在组件中设置一个div有固定大小,展示区域即为这个区域
<template>
<div id="ect" style="width: 100%;height: 300px;"></div>
</template>
<script setup>
import * as echarts from 'echarts'
const option = {
title: {
text: '测试'
},
tooltip: {},//提示框
legend: {
data: ['人数']
},
xAxis: {
data: ['vue', 'react', 'angular', 'jquery']
},
yAxis: {},
series: [
{
name: '人数',
type: 'bar',
data: [200, 400, 150, 3000],
}
]
}
onMounted(() => {
// charts
var myChart = echarts.init(document.querySelector('#ect'));
myChart.setOption(option)
})
</script>
