Yes, but the length of the arrow should correspond to the length of the
arrows drawn by partyvelec. Typically, you have a windfield to plot on
an image, and you now the (u,v) or your wind field and their (x,y)
positions in /data coordinates. for example, if your wind speed ranges
from 0 to 12. m.s-1, you might want to add a legend to your plot with an
arrow showing the length of a wind arrow of 10 m.s-1.

Anyways, I'll think about a version of partvelvec which provides an
ouptut structure (in /NORMAL coordinates) of the longest arrow it has
plotted and use cgArrow to draw the legend. This should be fine.

Thanks!
