Question: How do i get in plot line style to be of type line + symbol

Dear sir, can we get a plot of graph with line style like  line+symbol so on.. 

I am attaching codes and sample graph .

 

h:=z->1-(delta2/2)*(1 + cos(2*(Pi/L1)*(z - d1 - L1))):
K1:=(4/h(z)^4)-(sin(alpha)/F)-h(z)^2+Nb*h(z)^4:
lambda:=(F,Nb,delta2)->Int(K1,z=0..1):

L1:=0.2:
d1:=0.2:
alpha:=Pi/6:
A:=plot( [seq(seq(lambda(F,Nb,delta2), Nb=[0.1,0.2,0.3]), F=[0.1,0.2,0.5])],
          delta2=0.02..0.1, linestyle = [solid,longdash,dashdot],'
          thickness = 2',color=[red$3,blue$3,black$3],
          legend=["Nb=0.1","Nb=0.2","Nb=0.3",""$6]):
B:=plots:-textplot([[0.05,-1,F=0.1],[0.05,1.5,F=0.2], [0.05,3,F=0.5]], font=[times, 14]):

plots:-display(A, B);
