You can easily plot real quantities which are function of complex 
variables as for instance Abs[], Re[], Im[] like this


f[x_, y_] := 2*x + 3*I*y

Plot3D[Abs[f[x, y]], {x, -2, 2}, {y, -2, 2}];
Plot3D[Re[f[x, y]], {x, -2, 2}, {y, -2, 2}];
Plot3D[Im[f[x, y]], {x, -2, 2}, {y, -2, 2}];

Regards,
Wolfgang
