Echarts-数据可视化

       在实训中,利用Echarts、css、JavaScript以及HTML来制作的一个数据可视化界面,支持折线图(区域图)、柱状图(条状图)、散点图(气泡图)、K线图、饼图(环形图)、雷达图(填充雷达 图)、和弦图、力导向布局图、地图、仪表盘、漏斗图、事件河流图等12类图表,同时提供标题,详情气泡、图例、值域、数据区域、时间轴、工具箱等7个可交 互组件,支持多图表、组件的联动和混搭展现。

完成该项目需要具备以下知识:

div + css 布局
flex 布局
Less->CSS
原生 js + jquery 使用
rem 适配

Echarts

- 基于 flexible.js + rem 智能大屏适配
VScode cssrem 插件
Flex 布局
Less 使用
基于 ECharts 数据可视化展示
ECharts 柱状图数据设置
ECharts 地图引入

 所使用的软件:Visual Studio Code

四、总结

     以上代码只有部分,都是主要部分。其中js(china.js、echarts.min.js、flexible.js、jquery.js) 这些都需要去下载插件,可以去官网下载。css(index.css、index.less)中创建好就行,只需操作index.less,index.css就会自动同步。还用到字体美化,引用font配置文件。最后,如果不喜欢我上图的图形可以去官网自己搜索所需要的表格类型  。
