Hi Peter,

probably you must do so because in non-cartesian coordinates
the cartesian direction of the unit vectors depends on rho and phi

You can still look on the vector field in the rho-phi space but
it needs a lot of experience to understand form those pictures
what happens in the real space.

Hope that helps
