Ich gehe mal davon aus, dass Du gnuplot installiert hast. Damit das aufgerufen gewerden kann, musst Du pdflatex mit -shell-escape laufen lassen. Siehe dazu Wie aktiviere ich -Shell-escape in meinem Editor?

Jedenfalls läuft das Beispiel bei mir dann mit dem erwarteten Ergebnis durch.

(18 Nov '15, 15:16) esdd

gnuplot kann irgendwie nicht gefunden werden. Was muss ich tun, damit es erkannt wird?

(18 Nov '15, 15:27) runix

Um herauszufinden ob gnuplot richtig installiert wurde, gebe ich ja ins Terminal gnuplot ein. Dort erscheint dann "Der Befehl kann nicht gefunden werden."

(18 Nov '15, 15:34) runix

Wenn gnuplot installiert ist, aber nicht gefunden wird, dann musst Du den Ordner, in dem das ausführbare Programm liegt, eventuell noch in die Umgebungsvariable PATH eintragen.

(18 Nov '15, 18:08) esdd

Wie und wo genau mach ich das? Was meinst du mit -ausführbares Programm-?

(21 Nov '15, 13:43) runix

Kann mir das wirklich keiner erklären mit dieser 'PATH' Variablen?

(21 Nov '15, 18:52) runix

Ist zwar schon alt, aber hier für die Googler:

*nix: export PATH=$PATH:/path/to/gnuplot >> ~/.bashrc | source ~/.bashrc

(je nach shell muss .bashrc angepasst werden)

Windows: cmd.exe öffnen; set PATH=%PATH%;X:pathtognuplot

Der Pfad muss natürlich jeweils angepasst werden.

@maphy-psd: Normalerweise muss man bei Linux, das auch ein *nix ist, den Pfad nicht erweitern, wenn man gnuplot über den Paketmanager installiert. Auch die Installation unter OS X braucht das AFAIK nicht. Bei Windows kommt es darauf an, ob man die native Version als ZIP heruntergeladen und entpackt hat oder gleich cygwin verwendet. Wenn man unter Windows PATH erweitert, dann besser nicht nur einmal per set, sondern dauerhaft.
