  A flexible graphic display system for controlling the KEK Photon Factory storage ring has been developed. A VME computer locally controls the graphic display system and communicates with the host control computer through a RS-232C link. Graphic pictures are prepared in the local system by an interactive operation using either a tablet or a keyboard. The host control computer is free from any load due to graphics processing. In an on-line operation, pictures are displayed and modified by simple command strings from the host computer. A "picture stack" method has been developed for this graphics system. The latest demanded picture always has top priority to be presented on each display monitor. Previous pictures are saved in a stack and can reappear when the current picture has been freed.
