The vector chart represents data with angle and magnitude in lines. This sample shows the fluid direction and speed of the surface water for the days represented in the X-axis.

The <Vector2DChart> element tag is used to create a Vector chart in KoolChart, and the series element tag for the Vector chart is <Vector2DSeries>.
