Abstract: This paper solves real-time curve plotting problem by creating a new plotting data interface which has large expansibility and transplant behavior under an embedded GUI application. This GUI application is applied under the embedded Linux environment based on the PC/104 platform. A new low level plotting mechanism and method is created in order to solve the dynamic scale and glitter scream problem. The experiment result shows that they can solve the real-time plotting problem well under embedded application.

Key words: embedded Linux, MiniGUI, real-time curve, glitter scream, dynamic coordinate
