@Irving In the y-axis is displayed the name of the variable of the first plot listed in the display commands, but you have N1 N2 and N3 in the y axis, for labelling the three curves the only think I can think of is adding a legend, here is how you can do it in your case:

> T1:=textplot([40,0.5,'N1(t)']):T2:=textplot([40,0.3,'N2(t)']):T3:=textplot([40,0.1,'N3(t)']):
> L1:=plot([t,0.5,t=35..38],thickness=2,color=black): L2:=plot([t,0.3,t=35..38],thickness=2,color=yellow): L3:=plot([t,0.1,t=35..38],thickness=2,color=violet):

add those plots (Ti,Li i=1..3) in your display, and you will have a legend for the three lines in your graph.
