Angular pulsation with pyplot works as whishes : using PyPlot plt=PyPlot R=40;L=1/pi*360E-2;C=1/(pi*360E+2);ω=1/(sqrt(L*C)) fr=linspace(0,2ω) y=abs(1./(1+im.*fr.*R.*C-fr.*fr.*L.*C)); fig = figure("Angle") plt.plot(omega, y); plt.ylabel("z"); plt.xlabel("w"); ax = plt.gca() # get current axes ax[:set_xlim]((50,500)); ax[:set_ylim]((0,10)); plt.grid("on") plt.title("Pulsation angulaire"); round(ω) I am doing it with plots ... But I wish frequency resonance with plots (or even pyplot because I didn't make it work properly).
