4.3 Vectors
Vectors describe directed quantities in physics, such as forces or field strengths. For the representation of vectors, the Matplotlib module provides the quiver([X,Y],U,V, [C],**kwargs) method.
The [X,Y] list sets the initial coordinates of the vector. The U parameter determines the x-component, while the V parameter determines the y-component of the vector arrow. If you omit the [X,Y] parameter, then the start of the arrow is automatically placed at the origin of the coordinate system, and the arrowhead points to the specified u-v coordinate. The C parameter allows you to set the color of the vector arrow. The optional parameter **kwargs provides supplementary properties.
