Is there a straightforward way of plotting a vector in matplotlib?
Suppose I want to plot the vector [1 2]'. If I pass this vector in to

Is it possible to print the value of a variable in an annotation?
Example:
gradient = 2.0

xy=(2.9,-0.75), xytext=(2.9,-0.75))

familiar with figure, but apparently using it produces some canvas

What happens if I don't use figure? I just put a copy of the line

So far matplotlib pretty much leaves the user on his own. Yes, there are
plenty of examples, but there seem to be no explanations about matters
like figure or show. No tutor on any of this I guess. Apparently, they
are leaving it up to one's MATLAB experience. It's been
