Dit is dezelfde garfiek. Bij de ene link moest je de blocks op 5 zetten en bij de andere zoals hier is weergegeven (block =4)

Hieronder een link met blocks = 5

Goede grafiek.

Grafisch is er een sterke daling waar te nemen, alhoewel we duidelijk opmerken dat de productie slechts enkele eenheden daalt.

Dit is het antwoord op task 5 !!!

Door een foutje is de 'blockwidth' niet aangepast van 4 naar 5. Hieronder kan u een link terugvinden met het correcte antwoord. Opmerking! Er is een sterke daling waar te nemen alhoewel dit in werkelijkheid slechts enkele eenheden daalt.
