plt.subplots()練習

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

# First create some toy data:
x = np.linspace(0, 2 * np.pi, 400)
y = np.sin(x ** 2)

# Creates just a figure and only one subplot
fig, ax = plt.subplots()
ax.plot(x, y)
ax.set_title('Simple plot')

# Creates two subplots and unpacks the output array immediately
f, (ax1, ax2) = plt.subplots(1, 2, sharey='row')
ax1.plot(x, y)
ax1.set_title('Sharing Y axis')
ax2.scatter(x, y)

fig, axes = plt.subplots(2, 2, sharey='all')
axes[0, 0].set_title('Sharing Y axis at all')
axes[0, 0].plot(x, y)
axes[1, 1].scatter(x, y)
# Creates four polar axes, and accesses them through the returned array
fig, axes = plt.subplots(2, 2, subplot_kw=dict(polar=True))
axes[0, 0].plot(x, y)
axes[1, 1].scatter(x, y)
plt.show()
