vue使用datav echarts

一.分别使用下面两句下载datav和echarts

npm install echarts --save
npm install @jiaminghi/data-view

二.在main.js文件中全局注册组件

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import dataV from '@jiaminghi/data-view'
// 引入 echarts
import * as echarts from 'echarts'
Vue.prototype.$echarts = echarts

Vue.use(dataV)

Vue.config.productionTip = false

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

三.准备工作，因为没有对接后端所以只能使用静态文件

1.使用datav中的一些组件需要准备的文件，我们创建一个config.js,里面的config1~8都是为各datav各组件准备的不同的数据格式，每个组件需要的数据格式和写法不太一样，具体可以参考官方文档里的示例datav官网地址

const config1={} 
const config2={
    header: ['列1', '列2', '列3'],
    data: [
      ['行1列1', '行1列2', '行1列3'],
      ['行2列1', '行2列2', '行2列3'],
      ['行3列1', '行3列2', '行3列3'],
      ['行4列1', '行4列2', '行4列3'],
      ['行5列1', '行5列2', '行5列3'],
      ['行6列1', '行6列2', '行6列3'],
      ['行7列1', '行7列2', '行7列3'],
      ['行8列1', '行8列2', '行8列3'],
      ['行9列1', '行9列2', '行9列3'],
      ['行10列1', '行10列2', '行10列3']
    ],
    index: true,
    columnWidth: [50],
    align: ['center'],
    carousel: 'page'
}
const config3={
  data: [
    {
      name: '周口',
      value: 55
    },
    {
      name: '南阳',

}
const config4={}

2.datav内置的图表很多，但有的时候我们还是需要使用echarts来丰富图表，在使用datav的同时，我们想要使用echarts里的图表时需要将其写成组件，在components文件夹下创建echarts文件夹在里面创建line.vue文件，文件内容如下

<template>
        <div id="echartsID">

        </div>
</template>

<script>
export default {
    mounted() {
        this.echarts()
    },
    methods: {
        echarts() {
            let myChart = this.$echarts.init(document.getElementById('echartsID'))
            myChart.setOption({
                tooltip: {
                    trigger: 'axis'
                },
                legend: {
                    data: ['预测', '实际',],
                    bottom: 'auto',
                    textStyle: { //图例文字的样式
                        color: 'white',
                    },
                },
                grid: {
                    left: '3%',
                    right: '4%',
                    bottom: '3%',
                    containLabel: true
                },
                toolbox: {
                    feature: {
                        saveAsImage: {}
                    }
                },

                xAxis: {
                    type: 'category',
                    boundaryGap: false,
                    data: ['2022-1', '2022-2', '2022-3', '2022-4', '2022-5', '2022-6', '2022-7'],
                    axisLabel: {
                        rotate: 12,
                        textStyle: { //图例文字的样式
                            color: 'white',
                        },
                    },
                },
                yAxis: {
                    type: 'value',
                    axisLabel: {
                        textStyle: { //图例文字的样式
                            color: 'white',
                        },
                    },
                },
                series: [
                    {
                        name: '预测',
                        type: 'line',

                        smooth: true,
                        data: [120, 132, 200, 810, 390, 230, 210]
                    },
                    {
                        name: '实际',
                        type: 'line',

                        smooth: true,
                        data: [220, 182, 220, 930, 290, 330, 310]
                    }
                ]
            });
        }
    },
}
</script>

<style scoped>
#echartsID {
    width: 90%;
    height: 80%;
}
</style>

3.还有一些静态图片，在assets文件夹下放入图片文件“map.jpg”、“mapCenterPoint.png”、“mapPoint.png”,图片自取静态图片地址

四.准备工作做好了就可以开始写测试文件了，我是直接在HomeView.vue里写的

<template>
  <dv-full-screen-container class="container">
    <div class="content">
      <dv-border-box-11 title="中国河南省">
        <div class="container laoda">
          <div class="box left">
            <dv-border-box-1 class="border-box">
              <dv-water-level-pond :config="config8" class="charts" style="height:280px" />
            </dv-border-box-1>
            <dv-border-box-8 class="border-box">
              <dv-scroll-board :config="config2" class="charts" style="height:280px" />
            </dv-border-box-8>
            <dv-border-box-1 class="border-box">
              <!-- <dv-scroll-ranking-board :config="config3" class="charts" style="height:280px" /> -->
              <eline class="charts"></eline>
            </dv-border-box-1>
          </div>
          <div class="box center">
            <dv-border-box-1 class="border-box">
                <dv-flyline-chart-enhanced :config="config5" :dev="true" class="charts" style="height:800px"/>
            </dv-border-box-1>
        </div>
        <div class="box right">
            <dv-border-box-1 class="border-box">
                <dv-scroll-ranking-board :config="config3" class="charts" style="height:280px" />
            </dv-border-box-1>
             <dv-border-box-8 :reverse="true" class="border-box">
                <dv-conical-column-chart :config="config6" class="charts" style="height:280px;" />
            </dv-border-box-8>
            <dv-border-box-1 class="border-box">
                <dv-capsule-chart :config="config7" class="charts" style="height:280px" />
            </dv-border-box-1>
        </div>
        </div>
      </dv-border-box-11>
    </div>
  </dv-full-screen-container>
</template>
<script>
import eline from '../../src/components/echarts/line.vue'
import { config1, config2, config3, config4, config5, config6, config7, config8 } from "./config.js"
export default {
  components:{
      eline
		},
  name: "test1",
  data: function () {
    return {
      config1,
      config2,
      config3,
      config4,
      config5,
      config6,
      config7,
      config8
    }
  },
}
</script>
<style scoped>
.container {
  display: flex;
  flex-direction: row;
  background-color: #01132C;
}

.content {
  width: 100vw;
  height: 100vh;
  display: flex;
  flex-direction: row;
}

.left,
.right {
  width: 25%;
}
.center{
    width: 50%;
}
.charts {
  width: 90%;
  margin: 5%;
}

.laoda {
  margin: 5vh 2.5vw;
  width: 95vw;
  height: 92vh;
  display: flex;
  flex-direction: row;
  /* background-color: antiquewhite; */
}

.box {
  display: flex;
  flex-direction: column;
}
</style>

完成后的样子

这样差不多就完成了，可以在这个基础上去测试别的组件，准备好组件所需数据就行了。
