Hi,

Does anybody know how to adjust the length (or otherwise appropriately assign a value to the fixed-length vector) that appears in a legend of a quiver plot?

I am plotting a wind vector field using quiver and want to add a legend to provide a reference vector with an associated value. I can create the elegend and assign a value manually, but I have to resort to an inexact and ad hoc approach to properly a assign a value to what appears to be a fixed-length vector that shows up in the quiver legend. How can I precisely either change the length of the vector in the legend or assign a value to the fixed-length vector?

Many thanks!
