It extends the DataSet class. The vectors are defined as (x,y,dx,dy) where (x,y) is the position of the vector tail and (dx,dy) is the relative position of the head. It is to be used in conjunction with the Graph2D class and Axis class for plotting 2D graphs.<dl> <dt> <b>Version:</b> <dd> 1.3, 1996/10/23 03:30:22 <dt> <b>Author:</b> <dd> Leigh Brookshaw</dl><hr><a
