I'm using Plot [ndsolve] of a set of differential equations. Listplot won't seem to make a list of solutions. I want one populations to have initial conditions of 0 but then at a further time stage to have a vlaue of 1 and see how that changes.

hi i was wondering if anyone knew how to introduce different populations at diffrent times on the same plot on mathematica? Say i wanted population 1 have n = 10 at t=0, population 2 to have n=4 at t=0 and then introduce a new population at t=25 so that population 3 would have n= 0 initally but...
