基于ECharts的铁路物流数据可视化效果的实现

Realization of Visualization of Railway Logistics Data Based on ECharts

为了将从全国各省市年鉴中提取出来的铁路物流数据以更直观的方式展示,降低用户的使用门槛,在以文本化方式展示数据的基础上,提出了实现铁路物流数据可视化的功能。将铁路数据以可视化方式呈现有助于用户迅速地从海量的铁路物流数据中迅速获取到所需要的重要信息,也可以更加直观形象地表达数据所蕴含的信息,更易于用户寻找数据变化的趋势和规律以及发现数据之间更深层次的联系。应用Javascript语言的可视化图表库ECharts实现了对铁路物流Web项目中铁路物流基础指标数据以及综合指标数据的动态展示,可以展示各个模块随着年份的走势(折线图)或者占比(扇形图)情况。

To display the railway logistics data extracted from the yearbooks of various provinces and cities across the country in a more intuitive way and reduce the user's threshold for use,on the basis of displaying the data in a textual manner,the function of realizing railway logistics data visualization is proposed.Visualizing the railway data will help users quickly obtain the important information they need from the massive railway logistics data.It can express the information contained in the data more intuitively and visually.It is easier for users to look for trends and laws of data changes and discover deeper connections between data.Finally,the dynamic display of railway logistics basic index data and comprehensive index data in the railway logistics web project is realized by the use of visual chart library ECharts,which can display the trend(line chart)or proportion(fan chart)of each module with the year.
