From the six possible ways to map three variables, one solution is shown in the viewer. Which of the remaining five would actually be a better solution?

x = len, y = dose, color = supp

x = len, y = supp, color = dose

x = supp, y = dose, color = len

x = dose, y = supp, color = len

x = supp, y = len, color = dose

30 - dose 2.0 20. 1.5 len 1.0 0.5 10- vc supp
