 ========================
 First make sure that you can use gnuplot:
 * Execute "gnuplot" in your command line
-** Doesn't work: Look up where the binary is located (e.g. `C:\Programs\gnuplot\bin\gnuplot.exe`) and add it to your path (Windows + Pause -> System variables -> Path). Then try executing "gnuplot" in terminal again
-** remember: You have to use `-shell-escape`

+It is a good idea to separate gnuplot-code from LaTeX-code! (see plot.gnuplot)
+
+`-shell-escape` or `enable-write18` is NOT needed for this solution!
