Can someone give a simple example of a complex function that is harmonic but not analytic?

Thanks.

Natural examples are $\mbox{Re}\;z, \mbox{Im}\; z, \bar{z}$... –  1015 Mar 2 '13 at 20:35

$x{}{}{}{}{}{}{}{}{}{}{}{}{}{}$
You probably mean $z\mapsto\mathrm{Re}(z)$. –  Philippe Malot Mar 2 '13 at 20:20
