Der Befehlscode kann ohne weiteres in die Zwischenablage kopiert und in das Kommandozeilen-Fenster von Gnuplot eingefügt werden. Die Datei wird erstellt, indem nach dem Einfügen die ENTER-Taste betätigt wird (es sei denn, unterhalb der eingefügten Sequenz befindet sich ein Prompt -- in diesem Fall wurde der Code bereits ausgeführt und die Datei ist bereits erstellt worden!). Damit alles funktioniert, muss die .txt-Datei, die die Rohdaten enthält, WTI_brent_spread.txt genannt werden und im gleichen Verzeichnis liegen wie die gnuplot.exe (d.h. im bin-Ordner des Gnuplot-Installationsverzeichnisses). Die Crude oil spread.svg wird im gleichen Verzeichnis abgelegt werden (und wenn nicht dort, dann im Benutzer-Ordner Dokumente).
The command code can be copied to the clipboard and pasted into Gnuplot’s command line shell window. The file is created by pressing ENTER after pasting (unless there appears a prompt after the pasted sequence -- in this case the code has already been run!). In order to make it work properly the .txt file containing the raw data (see above) has to be named WTI_brent_spread.txt and has to be located in the same directory as the gnuplot.exe (i.e. the bin folder of the Gnuplot install directory). The Crude oil spread.svg will be saved in the same directory (and if not it might have been saved to the user’s folder Documents).
