Finding the twist angle of a Vector around axis Z

Hi all
I have the positions of a vector F as a function of time, and I need to find the twist around axis Z, so I need to project it on XY plane and then find the angle with one of X or Y axis.
I know how to do the 2nd part , but I have problem with the first part. I am not sure the quiver() will give me the right result.
Also, as an Idea, could I use the gradients of the vector F along X and Y and divide them on eachother to find the angle with X or Y ?

The message is clear. Check the dimensions of the inputs of the cross command. Again:
Please provide what you have as inputs.
Posting the complete code is a good idea also.
