python-matplotlibHow to add third Y axis

In order to add multiple Y axes, we need to call twinx() method multiple times and adjust Y axes positions:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
twin1 = ax.twinx()
twin2 = ax.twinx()

twin2.spines.right.set_position(("axes", -0.15))

p1, = ax.plot([0, 1, 2], "g-")
p2, = twin1.plot([1, 7, 5], "r-")
p3, = twin2.plot([4, 2, 3], "b-")

ax.set_xlim(0, 2)
ax.set_ylim(0, 3)
twin1.set_ylim(0, 8)
twin2.set_ylim(0, 4)

ax.tick_params(axis='y', colors=p1.get_color())
twin1.tick_params(axis='y', colors=p2.get_color())
twin2.tick_params(axis='y', colors=p3.get_color())

plt.show()ctrl + cgithub

`import matplotlib.pyplot as plt` loads Matplotlib module to use plotting capabilities	`.subplots(` creates set of charts on a single chart area
`twinx()` creates twin axes sharing `x` axis	`twin2.spines.right.set_position` reposition second `Y` axis so they will not overlap
`ax.plot(` plot first line (green one)	`twin1.plot(` plot second line
`twin2.plot(` plot third line	`.set_xlim(` set `x` axis range
`.set_ylim(` set `y` axis range	`.show()` render chart in a separate window

Usage example

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
twin1 = ax.twinx()
twin2 = ax.twinx()

twin2.spines.right.set_position(("axes", -0.15))

p1, = ax.plot([0, 1, 2], "g-")
p2, = twin1.plot([1, 7, 5], "r-")
p3, = twin2.plot([4, 2, 3], "b-")

ax.set_xlim(0, 2)
ax.set_ylim(0, 3)
twin1.set_ylim(0, 8)
twin2.set_ylim(0, 4)

ax.tick_params(axis='y', colors=p1.get_color())
twin1.tick_params(axis='y', colors=p2.get_color())
twin2.tick_params(axis='y', colors=p3.get_color())

plt.show()
