Plotting lines in matplotlib

>>> import matplotlib.pyplot as plt

To plot a line in matplotlib, use plot with the X coordinates as the first argument and the matching Y coordinates as the second argument:

>>> # A line from (1, 2) to (7, 11)
>>> plt.plot([1, 7], [2, 11])
[...]
>>> # Another line from (2, 6) to (8, 1)
>>> plt.plot([2, 8], [6, 1])
[...]
