How to use ECharts4Taro3 to achieve multi-language support for data visualization in the Vue project

With the widespread application of data visualization in various industries, multi-language support has become a need that cannot be ignored. Using the ECharts4Taro3 library in a Vue project, you can easily implement multi-language support for data visualization. This article will introduce in detail how to use ECharts4Taro3 to achieve multi-language support for data visualization in the Vue project, and provide corresponding code examples.

Introduction to ECharts4Taro3

ECharts4Taro3 is a chart library based on ECharts and Taro3 specially built for Taro3 developers. It provides a variety of chart types and flexible configuration options to facilitate developers to use charts for data visualization in Taro3 projects.

Multi-language support

In actual projects, it is often necessary to display different content according to the user's locale. For data visualization, multi-language support for chart titles, legends, prompt boxes, etc. also needs to be based on the user's locale. The following will demonstrate how to use Vue-i18n and ECharts4Taro3 to achieve multi-language support.

Step 1: Install dependencies

First, we need to install the related dependencies of vue-i18n and echarts4taro3 in the Vue project. You can use the following command to install:

npm install vue-i18n echarts4taro3 --save

Step 2: Create an i18n instance

In the entry file main.js of the Vue project, we need to create a i18n instance and load the corresponding language file. The sample code is as follows:

import Vue from 'vue'
import VueI18n from 'vue-i18n'
import messages from './i18n'

Vue.use(VueI18n)

const i18n = new VueI18n({
  locale: 'zh-CN', // 默认语言为中文
  messages
})

new Vue({
  router,
  store,
  i18n,
  render: h => h(App)
}).$mount('#app')

Step 3: Create language file

Create a i18n folder in the root directory of the Vue project, and create ## in the folder Two language files, #zh-CN.js and en-US.js. The sample code is as follows:

// zh-CN.js
export default {
  echarts: {
    title: '图表标题',
    legend: '图例',
    tooltip: '提示框'
  }
}

// en-US.js
export default {
  echarts: {
    title: 'Chart Title',
    legend: 'Legend',
    tooltip: 'Tooltip'
  }
}

Step 4: Use multi-language in components

In components that need to use multi-language, you can obtain the corresponding translation through the

$t method text and pass it to the corresponding property of the ECharts component. The sample code is as follows:

<template>
  <div>
    <react-echarts
      :option="chartOption"
      :lang="$t('echarts')"
    ></react-echarts>
  </div>
</template>

<script>
export default {
  data() {
    return {
      chartOption: {
        title: {
          text: ''
        },
        legend: {
          data: []
        },
        tooltip: {}
      }
    }
  }
}
</script>

Step 5: Switch language

Provides the function of switching language on the page, you can modify the

locale of the i18n instance Property to dynamically switch languages. The sample code is as follows:

<template>
  <div>
    <button @click="switchLocale('zh-CN')">中文</button>
    <button @click="switchLocale('en-US')">English</button>
  </div>
</template>

<script>
export default {
  methods: {
    switchLocale(locale) {
      this.$i18n.locale = locale
    }
  }
}
</script>

So far, we have completed the multi-language support for data visualization using ECharts4Taro3 in the Vue project. Through the above steps, we can dynamically display the corresponding chart content according to the user's language environment and improve the user experience.
