I am trying to create a wind vector plot and have been mostly successful (see attachment). I followed the Arrow Markers example in the IGOR manual and used my data. It is mostly what I am looking for, but I would like to have the arrow tails to all originate from the same y-coordinate. It appears the arrow markers in Igor are aligned along an arrow center line.
One way to do this is to deconstruct the wind vectors and adjust the y-coordinate individually for each arrow based on the y-component of each wind vector. But I don't know how to do that in Igor. Any help would be much appreciated. (My coding is pretty awful so I prefer not to share that here.)
