set arrscl
set arrscl size <magnitude>

Specifies arrow length scaling.

size              is the length of the arrow in plotting units (inches on the virtual page). A typical value would be 0.5 to 1.0.
magnitude    is the vector magnitude that will produce an arrow of the specified size.

Other arrow lengths will be scaled appropriately. If magnitude is not given, all the arrows will be the same length. Reset by clear or display.
