Realization Of Data Visualization Based On ECharts

With the rapid development of Internet technology,people are producing large amounts of data in all kinds of ways every day.The explosive growth of data in quantity and complexity has brought us into the age of big data.How to enable people to understand the data quickly and make effective use of the data and analyze the hidden valuable information is an urgent problem to be solved.Data visualization uses graphical means to map data into graphics,symbols and colors,which can convey the information clearly and effectively,improve people’s perception and understanding of data greatly,and facilitate people to further discover the rules from the data.The project belongs to a general data monitoring platform of the company.The data platform can receive a variety of data which needs to be displayed,and finally display the potential value of the data in the form of visual charts,and provide strong support for the staffs decision-making.Most of the existing data visualization tools can be divided into two categories,one is the visualization system for traditional users,this tool is usually customized highly according to specific data,lackling of scalability,the other is visualization library for developers,this tool requires the user to build their own platform,lacking of ease of use.This paper designs and implements a universal,high scalable visualization system which supports open data sources and flexible data visualization methods according to the shortcomings of existing visualization tools and project requirements,and makes some exploration work on solving related problems.The system uses B/S architecture.Front end and back end are both using MVC mode development.ECharts is selected as the key technology of visualization in browser-side to realize the key step of transforming the visual data to the graphics.Server-side use of the mainstream open-source framework SpringMVC +Spring + MyBatis + MySql for transaction processing.In addition,since some data of the project need to be displayed as multi-venn-chart,but the current visualization library does not set mapping method of multi venn maturity,this paper extends the existing visualization library to realize multi-venn-chart drawing.Experiments show that the system has completed its intended function and performs well in capability and has high practical value.
