How can I show the scale of my arrow in a quiver plot?

Hi!

If I want to display the scale of my arrows on a quiver plot I got from my u and v velocities, how can I set the scale bar in the figure so that the reader can look at my arrows and understand how they're size relate to the axis of the plot.

I attached a picture so that the question beocmes more convenient to you!

Oof. This is one of the many reasons I don't like dealing with quiver plots. There are a few tools on the File Exchange that may be useful, but I haven't used any of them myself:
