Plotting from Octave

[Spencer Buckner]

Sergei Steshenko asked about dependencies when building the program from 
source, the API, and more details regarding the plot-parameter files.
The program is a GNOME application and uses the GTK+ and GNOME 
libraries, including libgnomeui-2.0 and libgnomeprintui-2.2.  It was 
developed on a Fedora-8 GNU/Linux Intel Pentium-4 system.  The 
dependency list is long.  A makefile is included for compiling, 
installation, and removal.  Details regarding the plot-parameter file 
and everything else are given in the gsegrafix.xhtml help file, included 
in gsegrafix-1.0.1.tar.gz.  Eleven example plots with the octave code 
required to generate the data and the corresponding parameter files for 
producing the plots are included in the help file.

Soren Hauberg mentioned that the wxt terminal for gnuplot will give 
smooth curves.
I just tried to use a wxt terminal with gnuplot but found that the 
Fedora-8 versions of octave and gnuplot (octave 2.9.15 and gnuplot 4.2) 
don't seem to know about it.  The "set terminal" command in gnuplot does 
not list wxt as an available terminal type.  I see that octave 3.0 and 
gnuplot 4.2.2 are included in Fedora-9.  Maybe those versions include 
wxt-terminal capability.
I started writing the plotting program, pretty much as a hobby, in 2003 
to learn something about writing linux applications.  Also, I thought 
gnuplot was not easy to use for anything other than very simple plots 
and because I didn't think the plots looked very good.  I don't believe 
Pango and Cairo were available then.  There still seem to be a lot of 
questions about how to use gnuplot.
