 ========================
 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
