Vue and ECharts4Taro3 Quick Start: Learn to build data visualization applications in one hour
Introduction: Data visualization is an important part of modern web application development. It helps users understand and analyze data more intuitively. In this article, we will introduce how to get started quickly and build a simple data visualization application using Vue and ECharts4Taro3. The goal of this article is to help readers learn to use these two tools in just one hour.
Preparation
Before starting, please make sure you have Node.js and npm installed. If it is not installed yet, please download and install it first. Then create a new directory, open the command line, enter the directory and run the following command:
npm install -g @tarojs/cli
Create Taro3 project
Run the following command to create a new Taro3 project:
taro init myApp cd myApp
After running the above command, you will get a basic Taro3 project structure. After entering the project directory, run the following command to start the development server:
npm run dev:weapp
Then use the WeChat developer tools to open the dist directory under the project root directory to preview the effect.
Install Vue and ECharts4Taro3
Next we need to install Vue and ECharts4Taro3. Run the following command:
npm install vue echarts echarts-for-taro3 --save
Add ECharts4Taro3 component
The method of using ECharts4Taro3 in Taro3 is very simple. Open the src/pages/index/index.jsx file and make the following modifications:
import React, { Component } from 'react' import { View } from '@tarojs/components' import TaroECharts from 'echarts-for-taro3' export default class Index extends Component { config = { navigationBarTitleText: '数据可视化' } render () { const option = { title: { text: '柱状图示例' }, xAxis: { type: 'category', data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'] }, yAxis: { type: 'value' }, series: [{ data: [120, 200, 150, 80, 70, 110, 130], type: 'bar' }] } return ( <View className='index'> <TaroECharts echarts={echarts} option={option} style={{ height: '300rpx', width: '100%' }} /> </View> ) } }
Run the project
After saving the above modifications, return to the command line interface and run the following command to restart Compile the project:
npm run dev:weapp
Then refresh the WeChat developer tool to see that the ECharts histogram example has been presented on the page.
