Graphics, Plotting and Data Visualization
-----------------------------------------
gnuplot
=======
`gnuplot `__ is a command line driven
utility for creating 2-D and 3-D graphs. The official documentation is
available `here `__. The `brief tutorial
`__ here may also be a
good starting point.
The user mailing list is linked from the `Help
`__ page.
XFig
====
Besides creating drawings in `XFig `__,
one way I find it really useful is in using it to process exported
graphs from `gnuplot`. Plots created in `gnuplot` can be exported in a
format called the `fig` format (among others). Once exported in this
format, you can then open it in `XFig`, make any changes to it
(including using `LaTeX formulas `__)
and export it to one of the `supported formats `__.
Inkscape
========
`Inkscape `__ is a `feature rich
`__ vector image creation
tool. There are a number of `tutorials
`__ for getting started
and various mailing lists for seeking help and discussions are listed
`here `__.
dia
===
`Dia `__ can be used to create
diagrams and supports exporting to a number of other formats. A
mailing list is available `here
`__.
GGobi
=====
`GGobi `__ is a visualization program for
exploring high-dimensional data. Various resources for learning GGobi
are listed `here `__.
A `mailing list `__ is available
for seeking help.
Mayavi
======
`Mayavi `__ is a
software for 3-D data visualization. Documentation for getting started
with Mayavi is available `here
`__.
Others
======
The `GNU image manipulation program `__ and
`g3data `__ are other
software available.
