Octave is a computer program for performing numerical computations which is mostly compatible with MATLAB . It is part of the GNU Project. It is free software under the terms of the GNU General Public License.

GnuPlot is described as 'Gnuplot is a portable command-line driven interactive data and function plotting utility. It was originally intended as to allow scientists and students to visualize mathematical functions and data. It does this job pretty well, but has grown to support many non-interactive' and is a popular graphing calculator in the education & reference category. There are more than 50 alternatives to GnuPlot for a variety of platforms, including Windows, Mac, Linux, Web-based and Android apps. The best GnuPlot alternative is GNU Octave, which is both free and Open Source. Other great apps like GnuPlot are MATLAB, Matplotlib, GeoGebra and LabPlot.

High-level environment supporting numerical computation, visualization, matrix operations, algorithm development, custom interfaces, integration with external languages, symbolic and model-based simulation, and specialized toolboxes for fields like engineering.




Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. Matplotlib makes easy things easy and hard things possible.






GeoGebra is free and multi-platform dynamic mathematics software for learning and teaching. It has received several educational software awards in Europe and the USA.




GeoGebra does not run in text-only, i.e. headless mode, which is the primary usage scenario of GnuPlot.


LabPlot is a free, open source and cross-platform Data Visualization and Analysis software accessible to everyone and trusted by professionals.
