- 官方团队Baidu EFE team有出一个vue封装的echarts库vue-echarts 。但是这个库和自己在vue里面封装没有啥太大区别。仍旧摆脱不了针对一个图表写一个巨大的配置文件。
- 参考BizCharts对G2这个库的封装方式，对echarts进行了封装。相对而言API更方便使用
使用ts-transformer-keys，从echarts导出的XXOption自动生成vue组件props
yarn add vuecharts3
- 定义一个
Chart组件作为画布 - 将echarts官方配置项每一个配置项使用统一的工厂函数构造成

- 通过自定义组件实现官方切换图像的example
import { contextSymbol } from 'vuecharts3'
const TreemapSunburstTransition = defineComponent({
name: 'TreemapSunburstTransition',
inject: [contextSymbol],
setup() {
const { chart } = inject(contextSymbol)
const interval = ref()
const state = reactive({
data: null,
type: '',
})
const url = "https://fastly.jsdelivr.net/gh/apache/echarts-website@asf-site/examples/data/asset/data/echarts-package-size.json"
fetch(url).then(res => res.json()).then(data => {
state.data = data.children
console.log('data.value', data.children)
interval.value = setInterval(function () {
state.type = state.type == 'treemap' ? 'sunburst' : 'treemap'
console.log('state.type', state.type)
}, 3000);
})
onUnmounted(() => clearInterval(interval.value))
return () => state.type == 'treemap' ?
h(Treemap, {
id: 'echarts-package-size',
animationDurationUpdate: 1000,
roam: false,
nodeClick: undefined,
data: state.data,
universalTransition: true,
label: {

animationDurationUpdate: 1000,
