ComplexContourPlot
ComplexContourPlot[f, {z, zmin, zmax}] generates a filled contour plot of f as a function of z.
ComplexContourPlot[{f1, f2, ...}, {z, zmin, zmax}] generates contour lines for f1, f2, ....
ComplexContourPlot[f == g, {z, zmin, zmax}] plots contour lines for which f = g.
Examples
Plot contours of a complex function:
