Vector Chart

In This Topic

Vector charts display arrows in 2D or 3D space. A vector data item is defined by two points (begin - end) and is represented by a single arrow. An arrowhead is placed at the end point to indicate the vector direction. Vector Charts are commonly used to display force fields.
