Introduction

GSEGrafix is a GNOME application which uses an anti-aliased GNOME canvas for
creating scientific and engineering plots. The program is written in C and reads
ASCII plot-parameter files and data files. The plot-parameter files contain
keywords and corresponding arguments for specifying plot parameters (such as
data file names, data file formats, plot type, plot style, axis type, axis
labels, etc).

GSEGrafix can make rectangular two-dimensional plots (with linear, semilog, or
loglog axes), histograms, polar-axis plots, and three-dimensional plots (with
linear axes). Three-dimensional plots include points, contour, color, and mesh
plots. Data for three-dimensional plots can also be used to create two-
dimensional plots using contour lines or color to represent values of a third
variable.

A menu bar at the top of the plot window allows users to save the plot to a
file, send the plot to a printer, copy the plot to the GNU/Linux clipboard,
change the axis limits of the plot, change the orientation of three-dimensional
plots, and display mouse coordinates in the lower left corner of the plot window
for two-dimensional plots. All plots include options to add a grid, legend,
text, and date-time string to the plot. Additional images can be added to a plot
by specifying image file names and desired locations on the plot. Rectangular
two-dimensional plots include zoom capabilities using the mouse to specify a
rectangle on the plot to expand.

Details of the plot-parameter files, data files, and operation of the program
are given in the gsegrafix.xhtml help file. This file can be displayed before
installation of the program by extracting the program files from the compressed
archive file (as described in the INSTALL file) and opening gsegrafix.xhtml with
an appropriate application (Firefox, for example). After installation of the
program this file can be displayed with either of the following commands:

   $ gsegrafix -h   or   $ gsegraf -h
