Juelich Application Kernel System for Graphics with GKS

A graphic software package is presented, which is especially outlined for data processing in X-ray, neutron and electron spectrometers. It is superimposed on a reentrant GKS layer and offers an efficient and easy serving man-machine interface. It has capabilities of automatic scaling of axes and of interactive labelling of plots and handling of graphs. It works with symbolic instructions, data sets and device names. A 3D presentation is supported by the system.
