# How to fix the number and length of vectors when using ListVectorPLot

I want to plot only the vectors that I specify in my list of vectors, and no more. ListVectorPlot plots many of them, namely plots the field extrapolating from my four vectors.I would also like to have the length I give them, that is, if my list is the following:

list = {{{-1, -1},{2, -2}}, {{1, -1},{2, 2}}, {{1, 1},{-2,2}}, {{-1, 1},{-2,-2}}};

I would like to have just four vectors at sites {-1,-1},{1,-1},{1,1} and {-1,1} of length Sqrt[2²+2²].

Does anybody know how to do this?

Like Graphics[Arrow /@ {{{-1, -1}, {2, -2}}, {{1, -1}, {2, 2}}, {{1, 1}, {-2, 2}}, {{-1, 1}, {-2, -2}}}]? –  Guess who it is. May 28 '13 at 16:51
@J.M. this does not give the right angle of the vectors though. For example, I would like {2,2} to have 45º or {-2,-2} 225º and so on...Is this possible? –  Mencia May 28 '13 at 16:55
Like putting an origin of the vectors in each position. –  Mencia May 28 '13 at 16:57

 Graphics[Arrow[{#1, #1 + #2} & @@@ list]]
