The Vector graph or series is used to represent data as vectors (arrows) in
three-dimensional space. It has six mandatory series
StartY, StartZ, EndX, EndY, and EndZ. The
data in the first three components specify the positions of the start points of
the vectors while the data in the last three components specify the positions of
the end points of the vectors. The series also has an optional component called LabelMember
whose data may be used as the mark labels for the vectors.
The size of the vectors is determined by the ArrowHeight and ArrowWidth
properties. The appearance of the vectors is determined by the Pen,
StartArrow, EndArrow, StartArrowStyle,
and EndArrowStyle properties.
