The IDL iVector tool displays data in vector form. A vector is a line segment that has both length (magnitude) and direction. Magnitude and direction are expressed using two components, the "east-west" component (or U) and the "north-south" component (or V).
The iVector tool displays two-dimensional vector flow fields. Examples of data that can be visualized using vector flow fields are ocean currents, wind, and fluid flows. Data can be visualized as vectors (arrows), wind barbs, or streamlines, and can be located on a regular or irregular grid or can be georeferenced. You can control all aspects of these visualizations, including arrow style and size, coloring by magnitude, direction, or another dataset, data location, missing data, streamline particles, and subsampling.
