code, Ticks command is not working properly, that is, real axis range is not showing between $-2\pi$ to $2\pi$, where as imaginary axis is showing properly. Also, is there any command for complex list … plot and complex plot? I mean a command such that the following command works ComplexListPlot[w, Ticks -> {{-2π, -π, 0, π, 2π}, {-2π, -π, 0, π, 2π}}] instead of ListPlot[{Re[w], Im[w]}, Ticks -> {{-2π, -π, 0, π, 2π}, {-2π, -π, 0, π, 2π}}] …
