"Then how was this direction line drawn?"

It is drawn according to the direction of force applied to the magnetic pole or the charge at each point in the field .

There are indeed some points in the field where the quantity is the same, and these points can be connected to form lines or surfaces. For example, there are equipotential surfaces in the electrostatic field, and the electric potential of each point on the same equipotential surface is the same. However, the equipotential surfaces in the electrostatic field are not on the same electric line, but perpendicular to the electric lines. There are countless electric lines passing through the equipotential surface.
