来个需求，需要图形统计，以前写vue图形统计都是用echarts，时间紧迫，我就想echarts 有没有reactnative的插件？结果还真有。

安装

yarn add @wuba/react-native-echarts echarts

yarn add react-native-svg

import React, { useRef, useEffect,useState } from 'react';
import * as echarts from 'echarts/core';
import {View,Text,Image,Dimensions,TouchableOpacity} from 'react-native';

// echarts.use([SVGRenderer, LineChart, BarChart]);
echarts.use([
    SVGRenderer,
