[https://www.gnu.org/software/octave/ GNU Octave] is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. The program is named after [https://en.wikipedia.org/wiki/Octave_Levenspiel Octave Levenspiel], a former professor of the principal author. GNU Octave is normally used through its interactive interface ([https://en.wikipedia.org/wiki/Command-line_interface CLI] and [https://en.wikipedia.org/wiki/Graphical_user_interface GUI]), but it can also be used to write non-interactive programs. The project was conceived around 1988 and at first it was intended to be a companion to a chemical reactor design course. The GNU Octave language is largely compatible to [https://en.wikipedia.org/wiki/MATLAB Matlab] so that most programs are easily portable. In addition, functions known from the C standard library and from UNIX system calls and functions are supported. C/C++ and Fortran code can be called from Octave by creating [https://octave.org/doc/interpreter/Getting-Started-with-Oct_002dFiles.html Oct-Files], or using Matlab compatible [https://octave.org/doc/interpreter/Mex_002dFiles.html Mex-Files].
[http://www.octave.org GNU Octave] is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

::* Take a look at our [[Projects|project ideas]] and [[Summer of Code - Getting Started | Summer of Code project
All or most of the information about plotting in Octave can be found in the manual and on the internet. This information can be too scattered over different resources for a new user to find his/her way into solving a plotting problem/need. This tutorial should be considered as the 'recipe text' by examples if you consider the manual as a 'recipe ingredients only'.
ideas]].
* [[Recap of the hierarchy of each plot element]]
First of all, Octave aims at being compatible with Matlab (TM) as much as possible, so the graphics part is very similar too to Matlab. In Octave the first choice to make is the 'graphics_toolkit'. Standard is the 'gnuplot' toolkit using the Gnuplot software package (http://www.gnuplot.info). The second choice is 'fltk' (http://www.fltk.org). You might want to try to test both of them for your plotting aims to see which solves your problem.
