Research On Adaptive Visualization Technology Of Multi Source Heterogeneous Data Based On Model

With the rapid iteration of emerging information technologies,a large quantity of multi-source heterogeneous data has been generated in various application fields.How to integrate and process these data to mine valuable information has aroused a lot of attention and research in academia.Data visualization transforms data into different types of visual elements,which is a vital part of data processing and analysis process.Aiming at the problems of multi-source heterogeneous data visualization,this thesis studies the widget generation technology and the visualization dashboard construction technology based on widget in the visualization process.The main contents are stated as follows:(1)A model-based widget reconfigurable generation method is proposed.According to the generation principle of visual widgets,a method to quickly generate widgets through visual interface configuration is proposed.Firstly,the process of generating widgets from the traditional visualization library and the existing shortcomings are specifically analyzed.Then,a rapid widgets generation framework was proposed,and charts templates based on Echarts were constructed to generate widgets in a modelized manner.Finally,the concept of reconfigurable is introduced to realize the reconfigurable configuration of widgets.The experimental results prove that the framework integrates 36 cases of reconfigurable widget templates,which is superior to most similar tools in the types and quantity of integrated widgets,and the framework is extensible.In addition,comparison experiments with mainstream visualization libraries show that the widget constructed by this method has shorter initialization time and higher animation frame rate in performance.(2)A visualization dashboard agile construction method based on page adaptation is proposed.In view of the complex process of visual dashboard construction,a method for dynamically building adaptive dashboard based on widgets is proposed.First of all,the advantages and disadvantages of mainstream dashboard construction methods are compared,and the flexibility of building dashboards based on business intelligence tools is analyzed.Then,in the study of the mechanism of dynamic construction of dashboards,an agile construction framework for dashboards based on visualization widgets was proposed,and three adaptive solutions for dashboard pages were designed to realize the adaptive display of visualization results.Finally,a general tool for building agile dashboards was developed.The test results show that the dashboard built based on this tool has high usability and interactivity in function,and also performs well in terms of performance,which meets the visualization requirements of practical applications.(3)The case study of multi-source heterogeneous data visualization is realized.Based on the above research results,this thesis aims at the requirements of multisource heterogeneous data visualization,and uses the tool developed to quickly build a joint operation electromagnetic situation data visualization analysis platform.The key indicator data of complex and multi-source electromagnetic situation can be visualized and analyzed in real time.The case study results show that based on the proposed rapid widget generation method and visualization dashboard agile construction method can quickly build the corresponding data analysis platform for diverse visualization needs.Therefore,the research results have high application value for data visualization analysis in different fields.In addition,the visualization dashboard construction tool proposed has been well received in actual projects.
