如何利用Vue和ECharts4Taro3构建动态可切换的多维数据可视化页面

npm install -g @tarojs/clitaro init myProjectcd myProject

npm install echarts@^5.1.2 echarts-for-taro@^3.0.0 -S

<script>import ECharts from 'echarts-for-taro';import 'echarts-gl';// 在Vue中全局注册ECharts组件Vue.component('v-chart', ECharts);</script>

<template>  <view>    <v-chart :option="chartOption" @ready="chartReady"></v-chart>    <button @click="toggleChart">切换维度</button>  </view></template><script>import * as echarts from 'echarts/core';import { GLChart } from 'echarts-gl';export default {  data() {    return {      chart: null,      dimension: 0, // 当前显示的维度      dimensions: ['维度1', '维度2', '维度3'], // 所有维度选项      chartOption: {        ... // 初始化ECharts的选项配置      }    };  },  methods: {    // 初始化ECharts实例    chartReady(chart) {      this.chart = chart;      this.updateChart();    },    // 切换维度    toggleChart() {      this.dimension = (this.dimension + 1) % this.dimensions.length;      this.updateChart();    },    // 更新ECharts的选项配置    updateChart() {      this.chartOption = {        ... // 根据当前维度生成相应的ECharts选项配置      };      // 调用setOption方法更新ECharts实例      this.chart.setOption(this.chartOption);    }  }};</script>

<template>  <view>    <data-visualization></data-visualization>  </view></template><script>import DataVisualization from '@/components/DataVisualization';export default {  components: {    DataVisualization  }}</script>
