libsciplot1

widget for scientific plotting

The SciPlot Widget is a widget capable of plotting Cartesian or polar graphs, including logarithmic axes in Cartesian plots. The widget is subclassed directly from the Core widget class, which means that it does not depend upon any other widget set. It may be freely used with Athena, Motif, or the Open Look/Xview widget sets. (There is optional Motif support that causes the widget to be subclassed from XmPrimitive. See the man page.)

Utilities based on 'libpoppler' for extracting text, fonts, attachments and metadata from a PDF file. Also supports high quality rendering of PDF documents into PNG, JPEG, TIFF format, or into raw bitmap vectors for further processing in R.

libplplot17

Scientific plotting library

PLplot is relatively small, portable, freely distributable, and is rich enough to satisfy most users. It has a wide range of plot types including line (linear, log), contour, 3D, fill, and almost 1000 characters (including Greek and mathematical) in its extended font set. The package is designed to make it easy to quickly get graphical output; only a handful of function calls is typically required. For more advanced use, virtually all aspects of plotting are configurable.
