Question: How to get data from a plot?



restart:

 Different plots for Transcendental equation obatined for heat flux condition

H:=0.05;C:=1.96;k:=4;R:=20.02;

(1)

F:=1/(R*S+1-S);

(2)

B:=Pec_i/k*exp(-C*Pec_i*F/k*S)*Q*(H-1/(1-exp(-Pec_i)))-1/k*Pec_i*F*exp(Pec_i*F*(1-S))/(1-exp(Pec_i*F*(1-S))) = -H*Pec_i*F/k;

(3)

p1 := plots:-implicitplot([subs(Pec_i=10.05,B),subs(Pec_i=50.005,B),subs(Pec_i=80.0002,B)], Q=-60..90, S=0..1):plots:-display(p1);

 

I want to get data from the above plot.
