Graphics for real-time signal-processing systems
A graphics software package able to produce hardcopy plots of multi-channel (of the order of 100 channels) data for real-time applications is described. The system is implemented at present using a lineprinter with graphics capability, and is able to plot multi ple curves along or across the paper with full annotation. In addition, intensity modulated plots may be made for use in applications such as satellite imaging. Features of the system are multi-channel capability, small core requirements. and lack of restriction on plot length. Also described is a control technique for graphics ·programs whereby plots may be easily modified and plotting mode changed, allowing a high degree of flexibility as is required during on-line experimental work at sea
