Since you seem to be the documentation on this, I have one more (I
hope) question. I'm actually using a non-square aspect ratio in my
plot, so that I can overlay it on a rectangular image. I'm using
something like this:
data = Table[{x, y}, {y, 10}, {x, 20}];
ListVectorPlot[data, AspectRatio -> 1/2, VectorPoints -> {20, 10},
VectorStyle -> "RightDot", VectorScale -> {Automatic, 0.3}]
but this draws dots that are really squished. There doesn't seem to be
any natural way to draw non-square vector plots.
Is it possible to make the dots circular, so that they don't also
follow the aspect ratio?
Any ideas?
Thanks!
