## 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`.
