For a fixed point charge, the electric field line is not change with time.
And we will measure steady E field around the charge.

When the charge starts to oscillate , the Electric field line will change with time and produce electro-magnetic field.
This applet simulate a charged particle under simple harmonic motion and the electric field line is propagated.

Let's replace the point charge with a line charge in the vertical direction.
