i chime in to +1 for adding a plot attribute to RealSet (as a user, it was
among the 1st things i tried when i discovered this class), something like
`plot(RealSet(-oo, oo))`.
note that matplotlib allows to draw a plain horizontal line:
{{{
from matplotlib import pyplot as plt
plt.figure()
plt.hlines(1, -10, 10) # horizontal line
plt.eventplot([-1, 1], linelengths=0.1) # vertical markers
plt.axis('off')
plt.show()
}}}
playing with the parameters you can make it look nicer, such as drawing
right/left arrows indicating unboundedness (similar to the plot of
unbounded polyhedra), thicker horizontal line, to label -1, 1, and so on.
