首页 > 解决方案 > Matplotlib 固定子图高度

问题描述

我正在尝试绘制一系列已分割的字符,每个字符具有相同的高度,但相对宽度取决于分割是否成功。但是,这种变化的宽度正在影响子图的高度。有没有办法使这些子图中的每一个都具有相同的形状?我已经尝试了以下各项:

plt.axis('equal')
plt.axis('scaled')
width_ratios=[3, 1], height_ratios=[4, 1]
gridspec_kw={'width_ratios': [3, 1]}

在此处输入图像描述

在此处输入图像描述

fig, ax = plt.subplots(1, len(i))
for x in range (0, len(i)):
    ax[x].imshow(i[x])
    plt.savefig("img")

提前致谢

编辑 1:@Jody Klymak 建议

ax[x].set_xlim([0, 40])
ax[x].set_ylim([0, 50])

在此处输入图像描述

编辑 2:@a11 建议我实施了您的建议,但似乎没有效果。 在此处输入图像描述

fig, ax = plt.subplots(1, len(i), sharey=True, figsize=(10,10))
for x in range (0, len(i)):
    ax[x].imshow(i[x])
    ax[x].set_aspect(aspect='equal')

我会给他们同样的限制:

import matplotlib.pyplot as plt
import numpy as np

fig, axs = plt.subplots(1, 2)
axs[0].imshow(np.ones((15, 3)))
axs[1].imshow(np.ones((3, 15)))

for ax in axs:
    ax.set_xlim([0, 15])
    ax.set_ylim([0, 15])

plt.show()
