实现这个组件需要引入echarts和vue-echarts插件，使用vue-echarts是因为它帮我们封装了一些很常用的功能，比如监听页面resize后重新渲染功能，本次组件只使用到了autoresize配置，其它可以根据官方文档按需选配
https://github.com/ecomfe/vue-echarts
首先引入echarts和vue-echarts插件
npm install echarts vue-echarts -S
组件定义参数如下
import type { ECBasicOption } from 'echarts/types/dist/shared'
const props = defineProps({
// echarts options 传参
option: {
type: Object as PropType<ECBasicOption>,
required: true,
},
// 容器宽度
width: {
type: String,
default: '100%',
},
// 容器高度
height: {
type: String,
default: '400px',
},
})组件代码如下
<script setup lang="ts">
import { PropType, provide } from 'vue'
import type { ECBasicOption } from 'echarts/types/dist/shared'
import { use } from 'echarts/core'
import { CanvasRenderer } from 'echarts/renderers'
// 按需引入
import { PieChart, LineChart, FunnelChart, CustomChart } from 'echarts/charts'
import {
TitleComponent,
TooltipComponent,
LegendComponent,
GridComponent,
ToolboxComponent,
} from 'echarts/components'
import VChart, { THEME_KEY } from 'vue-echarts'
use([
CanvasRenderer,
PieChart,
TitleComponent,
TooltipComponent,
LegendComponent,
GridComponent,
LineChart,
ToolboxComponent,
FunnelChart,
CustomChart,
])
// 传入主题
provide(THEME_KEY, 'light')
const props = defineProps({
option: {
type: Object as PropType<ECBasicOption>,
required: true,
},
width: {
type: String,
default: '100%',
},
height: {
type: String,
default: '400px',
},
})
</script>
<template>
<div class="chart-container" :style="{ width, height }">
<VChart class="w-full h-full" :option="props.option" autoresize />
</div>
