With VectorPlot, I'd like to be able to draw vectors such that the
tail of the vector is at the center of the vector box, rather than
having the vector lines intersect the center in the middle of the
line. The result should be a grid of vectors such that the tails are
all on the grid points.
I've tried a variety of things with VectorStyle and VectorScale, but I
haven't found a way to make it draw only the second half of the vector
line.
I'm trying to make a pin vector plot like this:
ListVectorPlot[Table[{y, -x}, {x, -3, 3, 0.2}, {y, -3, 3, 0.2}],
VectorStyle -> Arrowheads[{{0.004, 0.5, Graphics[Disk[]]}}]]
but with the lines on only one side of the dots, while the dots remain
on grid points.
Any suggestions will be greatly appreciated!
