1.Echarts安装

终端运行安装命令：

npm install echarts -s

在main.js做全局引用：

//引入echarts
import * as echarts from 'echarts'
//vue全局注入echarts
Vue.prototype.$echarts = echarts;

 2.页面使用Echarts画柱状图和饼图

效果：

代码展示：

        <!-- 统计信息展示 -->
        <div style="display: flex; justify-content: space-around;margin-top: 36px;">
            <!-- 工作量统计 -->
             <div class="echart-work" ref="echartWork"></div>
            <!-- 库存统计 -->
            <div class="echart-work" ref="echartRepertory"></div>
        </div>
    mounted() {
        // 挂载完成dom后进行初始化
        this.showEcarts();
    },
