| China has always been a vast agricultural country, and agriculture is the foundation of the national economy, Agricultural price and people’s daily life are closely related. The sharp fluctuations in price of agricultural products have greatly impacted not only total receipts for producers, but also living standard of consumers. The price of agricultural products has some specific characteristics like tendency, regionalism, periodicity and seasonality, and to do researches on data visualization analysis technology, is mainly to study the visualization of time trend and spatial location of agricultural products price. In current data visualization analysis of agricultural prices, for lack of spatial price data of agricultural products, most studies focused on the researches of agricultural products price time trend, and visualization analysis of agricultural product price on spatial location are very few.As the rapid development and in-depth study of information technology like database technology, computer technology and Web technology, agricultural development needs more and more support of technology. With the rapid improvements of Internet of things of agriculture, the data generating from agricultural production, market and consumption are becoming more and more; it has become the inevitable requirements for agricultural informatization to find and show the valuable information from the mass data. As the lack and difficult acquisition of agricultural product price data, there are less applications of combination of visualization analysis technology based on time tendency and space location and the data of agricultural price data, and so as the visualization analysis on the data of agricultural price data.The paper, at first, studied the general information and the standard procedure of data visualization, focused on data and chart in data visualization, discussed the meaning of data visualization for agricultural price data, setting the theoretical basis for data visualization analysis of agricultural products.Secondly, the paper studied agricultural product price and its characteristics, did researches on the tendency, regionalism, periodicity and seasonality of agricultural products price and the characteristics of agricultural products price data like large data, difficult collection of overall process, lack of Authoritative data publishing agency, Isolated data system and difficult data share.Thirdly, on the basis, the paper did some analysis on data sources and data feature of the data in agricultural products monitoring and early warning database, and carried out in-deep study in arithmetic with system demand.Finally, according to the theory of visualization and modern information technology, agricultural product price data visualization system has been established. On the basis of system objectives and principle, with the java language, Spring framework, the function and database have been designed and established. The system of agricultural price data visualization was established based on time tendency and space location, in which some analysis were carried out on the time tendency and space location of agricultural price, providing the visual exhibition of agricultural product price data in all aspects, which is of great meaning for the visualization of agricultural product price. |
