Oh now I see... Neat. But you then need to have different ranges for the x variable.
using Plots x = linspace(-2, 2, 100) xh = linspace(0, 2, 50) xk = linspace(-2, 0, 50) f = sqrt(complex(4 .- x.^2)) g = -sqrt(complex(4 .- x.^2)) h = sqrt(complex(-xh.^2 .+ 2 * xh)) k = -sqrt(complex(-xk.^2 .- 2 * xk)) plot(real(f), x) plot!(real(g), x) plot!(real(h), xh) plot!(real(k), xk, show=true) readline()
