Hello All, I am using matplotlib0.8. With the quiver function I have tried to plot a vector. However for some reason I do not get what I want. I have problem with the S (according the comments a scaling parameter) parameter. When I set it to 0 (S = 0 ), I get the correct vector with correct direction, however the arrow head is not present. When I set it to 2 (S= 2) for instance, I get a scaling which I dont understand. The direction of my vector has changed. This is something which I do not want. I was wondering if this is a bug or whether it is my misunderstanding of this scaling parameter. What I want is no scaling (S=0) but then an arrow with an arrow head. A scaling might be useful in the future but then I think the direction should not changed, since a vector is characterized by its direction. Many thanks in advance for whoever that can help me out with this problem. Here below you can see my python code.
