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 refe
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')
The link provides more examples.
