not directly, but you could do this with some scripting. for example please
have a look at the 'draw vecfield' command script from
http://www.theochem.ruhr-uni-bochum.de/~axel.kohlmeyer/cpmd-vmd/part7.html#chap9_sect1

if you combine this with components from the dipole vector monitoring
script from:
http://www.theochem.ruhr-uni-bochum.de/~axel.kohlmeyer/cpmd-vmd/part3.html#chap5_sect2

you should be able to get what you want.

cheers,
