Colleagues, I see you widely use Mathematica. I have few suggestions.
1. type ";" after the Plot[...] operator; this saves one cm at the screen of the reafer.
2. Use colors (as bo198214 does), add argument ,PlotStyle->{RGBColor[0,0,0],RGBColor[1,0,0],...} ; then it is easier to see, where is the real part, where is the imaginary one.
3. Use ImplicitPlot function; then you can plot functions (for example, its real and imaginary parts) the complex plane, and by-pass the singularities which are usually at the real axix. Also, the cuts and branchpoints become seen.
4. Use copylefted C++ function conto, it plots contours better than Mathematica, but you need some programming; see the code and the example at
