 ====== Gnuplot ======
+Gnuplot может работать как в режиме интерактивной командной строки (когда команды вводятся в командную строку Gnuplot последовательно, один за другим), так и в неинтерактивном режиме (когда в Gnuplot передаётся сразу весь список команд, составленный заранее). Так, например, сценарий
 <code>
-gnuplot -e 'set terminal png; set ticslevel 2.5; set palette defined ( 0
+set terminal png;
- "black", 1 "dark-blue", 1000 "green", 2000 "yellow",3000 "red");set pm3d at bs; splot "sheet01.txt" with pm3d' | display
+plot "data2D.dat" with lines;
+</code>
-gnuplot -e 'set terminal png crop; set title "Sheet"; set view 60,10; set ticslevel 2.5; set palette defined ( 0 "black", 1 "dark-blue", 1000 "cyan", 1500 "green", 2000 "yellow",3000 "red");set pm3d at bs; splot "sheet23.txt" with pm3d notitle' | display
+можно выполнить одной командой следующего вида:
-gnuplot -e 'set terminal png crop; set title "Phase sheet 23" offset 0,-5; set view 60,10; set ticslevel 2.5; set palette defined ( 0 "black", 1 "dark-blue", 1000 "cyan", 1500 "green", 2000 "yellow",3000 "red"); set colorbox vertical user origin 0.9,0.1 size 0.03,0.7; set pm3d at bs; splot "sheet23.txt" with pm3d notitle' | display
+  gnuplot -e 'set terminal png; plot "data2D.dat" with lines;' | display
-gnuplot -e 'set terminal png crop size 600,800; set title "Phase sheet 23" offset 0,-10; set view 70,10; set ticslevel 1; set palette defined ( 0 "black", 1 "dark-blue", 1000 "cyan", 1500 "green", 2000 "yellow",3000 "red"); set colorbox vertical user origin 0.9,0.1 size 0.03,0.7; set ztics 0,500,3500; set pm3d at bs; splot "sheet23.txt" with pm3d notitle' | display
+Здесь сам Gnuplot генерирует PNG-файл с графиком, который тут же направляется в утилиту ''display'' из пакета [[imagemagick|ImageMagick]].
-gnuplot -e 'set terminal png crop size 600,800; set title "Phase sheet 23" offset 0,-10; set view 70,10; set ticslevel 1; set palette defined ( 0 "black", 1 "dark-blue", 1000 "cyan", 1500 "green", 2000 "yellow",3000 "red"); set colorbox vertical user origin 0.9,0.1 size 0.03,0.7; set pm3d at bs; splot "sheet32.txt" with pm3d notitle' | display
