vue大屏监控

vue 实现大屏监控

DataV介绍:DataV

样式如下所示:
vue大屏监控_第1张图片
vue大屏监控主要包括以下一些内容:

  1. 本次大屏监控页面包括三张图:两张柱状图、一张折线图
  2. 页面美化:引入DataV组件,用于大屏监控页面增加边框、装饰等
  3. 注意父子组件之间的彼此通信方法

以下代码顺序为:./components/下两个柱状图和一张折线图的代码;最后是screenMonitor父组件应用前述子组件代码

以上需要注意的是:

  • 父子组件通信:父组件向子组件进行通信,按照props进行传递;子组件向父组件通信使用this.$emit进行传递
  • DataV组件的style布局:可在前端页面element中进行调整,将调整结果复制至代码即可
  • 数据条颜色渐变:可使用new echarts.graphic.LinearGradient
