python - How I can get cartesian coordinate system in matplotlib?

Question

I am new to plotting with Python and can't really find an answer to the question: How can I get Cartesian coordinate plane in matplotlib? By this I mean perpendicular reference lines (coordinate axis) ended up with arrows, intersecting at the origin, (0,0), with the origin at the center of the plot.

Think about a a plane for doing high school geomtery, the following is a perfect example of what I need to achieve:

Answer 1

This is an old question, but I think with today's matplotlib versions, the keyword is spines. You would do:

ax = plt.gca()
ax.spines['top'].set_color('none')
ax.spines['bottom'].set_position('zero')
ax.spines['left'].set_position('zero')
ax.spines['right'].set_color('none')
