Vue框架下，如何实现实时监控的统计图表

npm install vue-chartjs chart.js socket.io-client

data() {  return {    chartData: [],  }},

created() {  const socket = io('your_socket_server_url');  socket.on('data', (data) => {    this.chartData = data;  });},

import { Line } from 'vue-chartjs';

export default {  extends: Line,  props: ['data'],  mounted() {    this.renderChart(this.data, this.options);  },}

<template>  <line-chart :data="chartData"></line-chart></template>

data() {  return {    options: {      responsive: true, // 图表自适应      maintainAspectRatio: false,      scales: {        xAxes: [{          display: true,          scaleLabel: {            display: true,            labelString: '时间',          },        }],        yAxes: [{          display: true,          scaleLabel: {            display: true,            labelString: '数据',          },        }],      },    },  }},

<style scoped>.line-chart {  width: 100%;  height: 400px;}</style>

watch: {  chartData() {    this.$data._chart.destroy(); // 销毁之前的图表实例    this.renderChart(this.chartData, this.options); // 重新渲染图表  },},

updated() {  if (this.data !== this.$data._data) {    this.$data._data = this.data;    this.$data._chart.update();  }},
