Abstract
The increasing number of test tasks lead to the rapid growth of test data. How to effectively and intuitively use the data has become the difficulty of the test data processing. Data visualization is the data is displayed by the modes of graphics and images, etc. it can effectively improve the data processing and interpretation capabilities, currently, and the data visualization has become an important means of the test data processing. Firstly, the test process, the flow of test data processing and the visualization requirements of the test data are briefly introduced. Secondly, the related technologies of the data visualization are deeply analyzed, the basic flow of data visualization, the interactive methods of data visualization and the realization tools of data visualization included. Thirdly, the types and characteristics of the test data are deeply analyzed, the basic flow the test data visualization is proposed, and the visualization of test data is presented. Lastly, for the dynamic geographical data of the test equipment, its visualization analysis and trajectory display are achieved. So, it can provide a reference for further research of the test data visualization.
