Full description
Accepts data files or stdin in a form similar to the unix program
graph and displays line graphs, scatter plots, or bar charts on an
X11 display. Fully annotated with title, axis numbering and
labels, and legend. Zooming with the mouse is supported. Can
generate hardcopy output to Postscript printers and HPGL
plotters. Output can be directly pasted into idraw (drawtool) for
further annotation. Particularly useful in shell scripts.
