什么是数据大屏？ 数据大屏是一种全屏展示的数据可视化方式，通常部署在企业的会议室、展厅或指挥中心。好的大屏需要兼顾"好看"和"有用"——既要有科技感的视觉效果，又要让数据一目了然。 设计原则 信息层次分明：核心指标放中间最大区域，辅助信息放两侧 深色背景：大屏环境光线通常较暗，深色背景减少眼疲劳 动效克制：适度的动画增加科技感，过多的动效分散注意力 自动刷新：数据定时刷新，30 秒到 1 分钟一次 技术实现 布局方案 我们选择了 Flex + vw/vh 方案，而不是 CSS Transform scale。Scale 方案虽然简单，但文字会模糊，echarts 的 tooltip 位置也会偏移。 .dashboard { display: grid; grid-template-columns: 1fr 2fr 1fr; grid-template-rows: auto 1fr 1fr; gap: 1.5vh; padding: 2vh 2vw; height: 100vh; background: #0a0e27; } ECharts 配置技巧 使用 resize 事件监听窗口变化，配合 ResizeObserver 自定义主题，统一颜色和字体 地图组件使用 GeoJSON 数据，支持省市下钻 大数据量使用 large: true 开启大数据模式 数据自动滚动列表 使用 CSS animation 实现无缝滚动，鼠标悬停时暂停。关键是复制一份列表数据拼接在末尾，动画从 0 滚动到 50% 后重置。 性能优化 只在数据变化时更新图表，使用 setOption 的 notMerge 参数 页面不可见时暂停刷新（Page Visibility API） 后端接口做缓存，避免频繁查库
What is a Data Dashboard? A data dashboard is a full-screen data visualization typically deployed in corporate meeting rooms, exhibition halls, or command centers. A good dashboard must balance "looking great" and "being useful" — delivering a tech-savvy visual experience while making data instantly comprehensible. Design Principles Clear Information Hierarchy: Core metrics in the center, supporting info on the sides Dark Background: Dashboard environments are usually dim — dark backgrounds reduce eye strain Restrained Animations: Moderate animations add tech appeal; too many distract attention Auto Refresh: Data refreshes every 30 seconds to 1 minute Technical Implementation Layout Strategy We chose Flex + vw/vh over CSS Transform scale. The scale approach is simpler but causes blurry text and misaligned ECharts tooltips. .dashboard { display: grid; grid-template-columns: 1fr 2fr 1fr; grid-template-rows: auto 1fr 1fr; gap: 1.5vh; padding: 2vh 2vw; height: 100vh; background: #0a0e27; } ECharts Configuration Tips Listen for resize events with ResizeObserver for responsive charts Custom themes for consistent colors and fonts Map components use GeoJSON data with province/city drill-down support Enable large: true for big data mode on large datasets Auto-Scrolling Data Lists CSS animation for seamless scrolling, pausing on mouse hover. The trick is duplicating the list data at the end, animating from 0 to 50% then resetting. Performance Optimization Only update charts when data changes, using setOption's notMerge parameter Pause refreshing when the page is not visible (Page Visibility API) Cache backend API responses to avoid frequent database queries
