The vector chart represents data with angle and magnitude in lines. This sample shows the fluid direction and speed of below-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>.
... <Vector2DChart ... > ... <series> <Vector2DSeries ... velocityField="speed1" degreeField="degree1" > ... </Vector2DSeries> </series> ... </Vector2DChart> ...
|velocityField||The velocityField attribute is to set the value of angle.|
|degreeField||The degreeField attribute is to set the field name for the value of angle.|
