What: gnuplot Where: http://www.gnuplot.info/ http://gnuplot.sf.net/ http://sf.net/projects/gnuplot/ ftp://ftp.gnuplot.vt.edu/pub/gnuplot/ Description: Gnuplot is a command-line driven interactive function plotting utility for UNIX, MSDOS, VMS, and many other platforms. Updated: 12/2002 Contact: See web site People often ask about combinations of gnuplot [ftp://ftp.gnuplot.vt.edu/pub/gnuplot] and Tcl; in fact, archives from [the comp.lang.tcl newsgroup] pertaining to gnuplot are quite extensive [http://groups.google.com/groups?q=gnuplot+group%3Acomp.lang.tcl*&num=25&hl=en&scoring=d]. Perhaps the most impressive marriage of the two is UniGNUPlot [http://unicalculus.sourceforge.net/], which makes for quick development of useful graphs: "Just with simple 'click' and scroll bars, you have a good graphic in seconds, ready to insert in the document what you want or directly to the printer..." gnuplot handles real and complex data. plotting specific columns i.e "using 1:3" or computations i.e "using ($1-$2):(abs($3) - pow($5,2))" from composite data is rather easy. Aside from plotting datasets gnuplot can handle functions i.e. f(x) = ax + bx² .. . As an encore gnuplot can fit functions to given data. ---- See also [3D animation on canvas with Gnuplot] ---- [[ [Category Application] | [Category Graphics] | [Category Plotting] ]]
