pxgraphprogram draws a graph on an X display given data read from either data files or from standard input if no files are specified. In Ptolemy, this program is invoked by several stars in several domains, and by the plot command in
pigi. The program is also available for stand-alone use, independent of Ptolemy.
Pxgraphcan display up to 64 independent data sets using different colors and/or line styles for each set. It annotates the graph with a title, axis labels, grid lines or tick marks, grid labels, and a legend. There are options to control the appearance of most components of the graph.
Pxgraphis a slight variant of
xgraph, modified to handle unusual IEEE floating-point numbers such as Inf and Nan, and to accept binary as well as ASCII input.
