You may have a scaling problem for showing it, but for example:

L:=[0.5, 1.0. 2.0, 5.0, 10.0]; # use an ordered list, not a set

P:=NULL;
for t in L do        # run through the list
   eval(J, nu=t);     # evaluate expression
   plot(%, T=0 .. 1); # plot for each
   P:=P, %;           # remember it
end do:

plots[display](P);   # print
