1)单行,或者单列
fig, axes = plt.subplots(nrows=1, ncols=2)
for ax in axes:
ax.plot(x, y, 'r')
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_title('title')
2)多行多列
fig, axes = plt.subplots(nrows=3, ncols=2, sharex=True)
# 此处不能用 for ax in axes:
for i in range(6):
axes[i//2, i%2].plot(x, y, 'r')
axes[i//2, i%2].set_xlabel('x')
axes[i//2, i%2].set_ylabel('y')
axes[i//2, i%2].set_title('title')
