如何实现可视化大屏

有没有想过这些是如何实现的呢？

实现方式

其实 实现这些并不是特别的困难 如下面方式

1. 易知微

2. 阿里DataV

个人实现

其实不然上面两种方式都是需要付费，对普通用户来说极不友好！ 由此我们可以自己来实现这些效果,以Vue为例只需要把各个显示的区域封装成组件即可,可以参考以下内容

1. Echarts

2. Vue

3. DataV

以下图为例，只需要把每个红色框内的内容封装成组件, 以下封装并不全面.具体封装请看参考！

头部封装

<template>
  <div id="top-header">
    <dv-decoration-8 class="header-left-decoration" />
    <dv-decoration-5 class="header-center-decoration" />
    <dv-decoration-8 class="header-right-decoration" :reverse="true" />
    <div class="center-title">施工养护综合数据</div>
  </div>
</template>

<script>
export default {
  name: 'TopHeader'
}
</script>

<style lang="scss">
#top-header {
  position: relative;
  width: 100%;
  height: 100px;
  display: flex;
  justify-content: space-between;
  flex-shrink: 0;

  .header-center-decoration {
    width: 40%;
    height: 60px;
    margin-top: 30px;
  }

  .header-left-decoration, .header-right-decoration {
    width: 25%;
    height: 60px;
  }

  .center-title {
    position: absolute;
    font-size: 30px;
    font-weight: bold;
    left: 50%;
    top: 15px;
    transform: translateX(-50%);
  }
}
</style>
