ehcarts快速上手网址:https://echarts.apache.org/handbook/zh/get-started/

echarts示例网址:https://echarts.apache.org/examples/zh/index.html

项目目录文件结构:

 plugins文件夹下的echarts.js文件(固定写法,后面只需要按案列更改option即可):

/* echarts图表库 */
import * as echarts from 'echarts'

export default {    
    /* echarts挂载到vue全局 */
    install:app=> {
        app.config.globalProperties.$line = (element)=>{
            // 加载echarts图表
            var myChart = echarts.init(document.getElementById(element));
            const option = {
                title: {
                    text: 'Stacked Line'
                },
                tooltip: {
                  trigger: 'axis'
                },
                legend: {
                  data: ['衬衫', '连衣裙', '休闲裤']
                },
                grid: {
                  left: '3%',
                  right: '4%',
                  bottom: '3%',
                  containLabel: true
                },
                toolbox: {
                  feature: {
                    saveAsImage: {}
                  }
                },
                xAxis: {
                  type: 'category',
                  boundaryGap: false,
                  data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
                },
                yAxis: {
                  type: 'value'
                },
                series: [
                  {
                    name: '衬衫',
                    type: 'line',
                    stack: 'Total',
                    data: [150, 232, 201, 154, 190, 330, 410]
                  },
                  {
                    name: '连衣裙',
                    type: 'line',
                    stack: 'Total',
                    data: [320, 332, 301, 334, 390, 330, 320]
                  },
                  {
                    name: '休闲裤',
                    type: 'line',
                    stack: 'Total',
                    data: [820, 932, 901, 934, 1290, 1330, 1320]
                  }
                ]
            };
            // 使用刚指定的配置项和数据显示图表。
            myChart.setOption(option);
        }
    }
}

option图表选项设置配置获取如下,打开示例网址:

main.js文件(配置全局):

import { createApp } from 'vue'
import { createPinia } from 'pinia'
import piniaPersist from 'pinia-plugin-persist'
import App from './App.vue'
import router from './router'
import './assets/init.css'
import elementIcon from "./plugins/icons";
import echarts from './plugins/echarts.js'

const app = createApp(App) // 创建app实例
const pinia = createPinia() // 创建pinia实例
pinia.use(piniaPersist) // 持久化存储
app.use(pinia) // 挂载pinia
app.use(router) // 挂载路由
app.use(elementIcon) // 挂载element-plus的图标
app.use(echarts) // 挂载echarts
app.mount('#app')
