That’s a good question. The short answer is no, ParaView does not have that type of annotation.

The only way I can think of to do it (other than programming something entirely new in ParaView) is to create your own annotation, although doing so will probably be vexing. To do that, you can add an `Arrow` source or a `2D Glyph` source with `Glyph Type` as `Arrow` to add a single arrow to your view of unit length. You can then use the `Transform` filter to move the arrow to an appropriate part of the view and scale it as appropriate. You would then have to add a `Text` source to give an appropriate label for the scale. You will have to do the math yourself to determine the scale based on the scaling of the arrow and the `Scale Factor` of the `Glyph` filter.
