People often ask about combinations of gnuplot [L1 ] and Tcl; in fact, archives from the comp.lang.tcl newsgroup pertaining to gnuplot are quite extensive [L2 ]. Perhaps the most impressive marriage of the two is UniGNUPlot [L3 ], 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.
