Isogram addition with line, histogram, and Lorenz plot is latterly realized in HBACIS so that the results of the inquiring, calculating and analyzing of the climate information can be visually displayed. The successful exploitation of HBACIS shows that the B/S system adopted JSP can totally satisfy the requirement of the agricultural climate information system. For one thing, JSP with the characteristics of high efficiency and security, multiplatform and expansibility, basing on the object oriented language-JAVA, can be sustained widely, and is easy to exploit and maintain. The JSP tags can be extended and the components are reused. For another, the client side of the B/S system is all applied with the browser as the interface, which is very simple and wieldy.
