Gist is a scientific graphics library written by David H. Munro of Lawrence Livermore National Laboratory. It features support for three common graphics output devices: X-Windows, (Color) PostScript, and ANSI/ISO Standard Computer Graphics Metafiles (CGM). The library is small (written directly to Xlib), portable, efficient, and full-featured. It produces x-vs-y plots with ``good'' tick marks and tick labels, 2-D quadrilateral mesh plots with contours, vector fields, or pseudocolor maps on such meshes, and a selection of 3-D plots.

The Python Gist module utilizes the ``Numerical'' package due to J. Hugunin and others. It is therefore fast and able to handle large datasets. The Gist module includes an X-windows event dispatcher which can be dynamically added to the Python interpreter. This makes fast mouse-controlled zoom, pan, and other graphic operations available to the researcher while maintaining the usual Python command-line interface.
