Plotting is the process of depicting mathematical functions or data visually. Before widespread use of computers, curve sketching or plotting was usually done by hand, often on special graph paper. Now most plots are made using dedicated computer plotting programs such or plotting features in larger programs.
Plot programs
Dedicated plot programs:
- Gnuplot - Open Source, very powerful, command-line driven
- http://descartes.sourceforge.net/ - Open Source (GPL), GUI-driven, Python-scripting language in the background, operating-system independent
- Xmgrace - Open Source (GPL), primarily for Linux
- http://www.mathe-online.at/fplotter/fplotter.html - Java-Applet
- - another Java-Applet (http://www.arndt-bruenner.de/mathe/java/plotter.htm)
- http://www.mathe-fa.de/ PHP server based
- http://www.funktionsplotter.de.vu/ another PHP server based solution
Larger programs that include a plot facility:
- computer algebra systems like Maple, Mathematica, yacas, Maxima
- data analysis software like Igor Pro, Matlab, Scilab, GNU Octave
- spreadsheets like oocalc, Microsoft Excel
