ListVectorPlot[ ] absolute, definite vector length
Posted: Aug 9, 2013 1:47 AM

Dear Group,

is it possible to plot vectors of definite length using ListVectorPlot ?

I am trying to plot vectors starting from specified (grid) points.
I would like that the vectors would be drawn exact with their length's relative to the units of the given gridpoints.

To do so I use VectorPoints -> All to get only the vectors in the data (no intermediate interpolated vectors)
and VectorStyle -> "LeftArrow" to start the vectortails from the grid points.

What is further neeeded is an absolut VectorScale (not relative to the plot).

The Example below draws Vectors with a length of about 0.41 I would like the length's to be eact 1.0 is this in general possible with ListVectorPlot?

ListVectorPlot[Table[{{x, y}, {1, 0}}, {x, -2, 2, 1}, {y, -2, 2, 1}],
VectorPoints -> All, VectorStyle -> ("Left" <> "Arrow"),
