Thanks to all, it's solved for the frequency resonance graphic(I change x and y value to 20,80 to put it in the center( I will look for doing it automatically). I will make a new one to get rid of all remarks I have done. But I have still problem with double graphic each time, I run it.
using Plots #pyplot(reuse=true) #plt=PyPlot R=40;L=1/pi*360E-2;C=1/(pi*360E+2);w=1/(sqrt(L*C)) f=1/(2.*pi*sqrt(L*C)) #omega=2*pi*f fr=linspace(20,80,100) y= abs(1 ./ (1+im*2*pi*fr*R*C-(2*pi*fr).^2*L*C)) #using Plots #y=abs(1./(1+im.*fr.*R.*C-fr.*fr.*L.*C)); plot(fr,y,title="Resonance frequency", bg=RGB(.2,.2,.2),xlabel ="Hz",ylabel = "Ω") Le jeudi 16 juin 2016 17:09:33 UTC+2, Henri Girard a écrit : > > Tom, > I have double graph each time in jupyter, before I didn't have this > problem with plots ? one is white without grid and the second on is right > with black theme ? > Any help about this ? > > Le jeudi 16 juin 2016 09:22:12 UTC+2, Henri Girard a écrit : >> >> Hi, >> When I make my plots I have two plots, but before I hadn't this... >> w is the resoning frequency, but it should appear at 0 (zéro) not at >> extrem ? >> Any help, I already ask for help with pyplot, this link : >> https://groups.google.com/forum/#!topic/julia-users/EJSvutfdEus, which >> works fine for angular pulsation, but I want frequency resonance with Plots >> because I guess I can make more beautifull graphic (anyway I don't know >> well PyPlot or Plots).
