The information for the arrow when you draw a vector image in ferret, seems to be in a correct location.
This option is useful for change the position of the arrow of vector information.
Just add this line in a journal script in ferret as following.
ppl veckey, xpos, ypos
(vecky is the vector information, xpos and ypos means the position of it)
ppl veckey, 0, 0, , (f4.0, “m s^-^1”)
- u,v: wind variables
- nolab: do not show the labels.
- len=0.2 : set the length of the vector
- set: necessary for applying ppl option
Done, hope you could find its changed position.
So, Simple 🙂
