I think you've misunderstood the "using" syntax of "with vectors".
The second triplet of numbers are the vectors lengths, not the
absolute coordinates of it's endpoint. Right?

Funnily, after stripping you script of all unnecessary decoration,
it does show a small weirdness: Why do we get a colourbar next to
this plot? It goes away after removing the "arrowstyle"s. (gp5.01)

$vectors << EOD
