Omit joining lines in matplotlib plot e.g. y = tan(x)

Question

I have the graph y = tan(x) and I want to remove the vertical lines (see below).

Here is my code:

import numpy as np
import matplotlib.p         


        

Answer 1

If you're willing to have the overhead of a more powerful mathematical program, SageMath can help with this:

plot(tan(x),(x,-2*pi,2*pi),detect_poles=True,ymin=-2,ymax=2,ticks=[pi/2,None],tick_formatter=pi)

(The little opening at the origin is something I've not seen before, hopefully fixed again soon.)
