课程名称:Vue + EChart 4.0 从0到1打造商业级数据报表项目

课程章节重构核心指标组件之销售组件日期组件
课程讲师: Sam

课程内容:
使用vue-echart重构,重构的样式会很简洁,无关的样式比如获取DOM等都可以删除了
创建公共的style样式
src/style/index.css

	.echarts {
	  width: 100%;
	  height: 100%;
	}
	.el-card__header {
	  border-bottom: none;
	  padding: 0;
	}

在mian.js中引入css

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import './plugins/element.js'
import './plugins/vcharts'
import ECharts from 'echarts'
import VueECharts from 'vue-echarts'
import './style/index.css'  // 新增

Vue.config.productionTip = false
Vue.prototype.$echarts = ECharts
Vue.component('v-chart', VueECharts)

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

重构累计订单TotalOrders

<template>
  <common-card
    title="累计订单量"
    :value="orderToday"
  >
    <template>
      <v-chart :options="getOptions()" />
    </template>
    <template v-slot:footer>
      <span>昨日订单量 </span>
      <span class="emphasis">{{orderLastDay}}</span>
    </template>
  </common-card>
</template>

<script>
  import commonCardMixin from '../../mixins/commonCardMixin'
  import commonDataMixin from '../../mixins/commonDataMixin'

  export default {
    mixins: [commonCardMixin, commonDataMixin],
    methods: {
      getOptions() {
        return this.orderTrend.length > 0 ? {
          xAxis: {
            type: 'category',
            show: false,
            boundaryGap: false
          },
          yAxis: {
            show: false
          },
          series: [{
            type: 'line',
            data: this.orderTrend,
            areaStyle: {
              color: 'purple'
            },
            lineStyle: {
              width: 0
            },
            itemStyle: {
              opacity: 0
            },
            smooth: true
          }],
          grid: {
            top: 0,
            bottom: 0,
            left: 0,
            right: 0
          }
        } : null
      }
    }
  }

学习到了如何使用vue-echarts对现在的业务进行重构,深入链接了,date-picker代码实现的原理,查看源码实现自定义参数,还可以根据自己项目需求自定义一周,一个月,一年的实现,更加贴近项目的需求,在vue-echarts中只要是自,自定义每个组件的:options,然后跟据需要展示的内容,配置固定的参数就可以实现了,vue-echarts配置细节确实需要了解透彻,然后知道如何查看源码,才可以更快的,更加有效的完成项目的需求,期待后面认真的学习ing
