python绘图subplots函数使用模板的示例代码

plt.rcParams['font.sans-serif'] = ['SimHei'] # 显示中文

from skimage import data
from matplotlib import pyplot as plt

moon = data.moon()
camera = data.camera()
image_minus = moon - camera
image_plus = moon + camera
# 绘图
plt.rcParams['font.sans-serif'] = ['SimHei'] # 显示中文

plt.subplot(2, 2, 1)
plt.title('月亮图像')
plt.imshow(moon)

plt.subplot(2, 2, 2)
plt.title('摄影师图像')
plt.imshow(camera)

plt.subplot(2, 2, 3)
plt.title('月亮加摄影师图像')
plt.imshow(image_plus)

plt.subplot(2, 2, 4)
plt.title('月亮减摄影师图像')
plt.imshow(image_minus)

plt.tight_layout()
plt.show()

from skimage import data
from matplotlib import pyplot as plt

moon = data.moon()
camera = data.camera()
image_minus = moon - camera
image_plus = moon + camera
# 绘图
plt.rcParams['font.sans-serif'] = ['SimHei'] # 显示中文
fig, axs = plt.subplots(2, 2)

axs[0, 0].imshow(moon)
axs[0, 0].set_title("月亮图像")

axs[0, 1].imshow(camera)
axs[0, 1].set_title("摄影师图像")

axs[1, 0].imshow(image_plus)
axs[1, 0].set_title("月亮加摄影师图像")

axs[1, 1].imshow(image_minus)
axs[1, 1].set_title("月亮减摄影师图像")

plt.tight_layout() # 子图之间合理间距
plt.show() # 显示图像
