PM3d map and plotting lines

[FrankMe]

Hi,

I'm using pm3d map to plot the field around a particle. Now I want to add also the shape of the particle in plot, but unfortunately I have no idea how. So my question is, is it possible (and in the case it is how?) to add a close curve (more or less an ellipse) in a pm3d map-plot?

Thanks in advance

set object <n> ellipse at <x>,<y> size <dx>,<dy> front

Thanks for your answer. but unfortunately I want to plot a disturbed ellipse (an ellipse with a hump), is it also possible? I think I have to add a parametric line in the pm3d map plot.
