Jag försöker att få till två kurvor i samma bild men får inte till det i RRdtool.
Den skriver ut en korrekt men den andra skrivs inte ut. Jag får inga felmeddelanden eller något, men det är säker något jag missat så min fråga till er är om ni kan se vart felet är? Bifogar även grafen som den ser ut
Här är mina filer:
