python - 如何删除一段 matplotlib 轴

Question

我想要一个像图中所示的情节:


这是我的 Python3 代码:

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(0.1,1.1,step=0.1)
y = np.array([0.03,0.03,0.05,0.05,0.06,0.17,0.44,1.37,4.43,6.89])
err = np.array([0.02,0.03,0.05,0.06,0.07,0.23,3.61,4.70,1.2,0.7])

fig, ax = plt.subplots(figsize=(10,8))

ax.errorbar(x,y,yerr=err)

ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
ax.spines['bottom'].set_position(('axes',-0.02))
ax.spines['left'].set_position(('axes',-0.02))

ax.set_xticks(np.arange(0.0,1.21,0.2))
ax.set_yticks(np.arange(0,11,2))

ax.set_xlabel('X')
ax.set_ylabel('Y')

plt.show()

从上面的代码，我得到这个情节:


如果我使用 ax.set_ylim([0,10])而不是 ax.set_yticks(np.arange(0,11,2)) ，我得到下图截断了误差条:


任何线索将不胜感激。

Answer 1

使用 ax.spines['left'].set_bounds(0, 10) .

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(0.1,1.1,step=0.1)
y = np.array([0.03,0.03,0.05,0.05,0.06,0.17,0.44,1.37,4.43,6.89])
err = np.array([0.02,0.03,0.05,0.06,0.07,0.23,3.61,4.70,1.2,0.7])
fig, ax = plt.subplots(figsize=(10,8))

ax.errorbar(x,y,yerr=err)

ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
ax.spines['bottom'].set_position(('axes',-0.02))
ax.spines['left'].set_bounds(0, 10)

ax.set_xticks(np.arange(0.0,1.21,0.2))
ax.set_yticks(np.arange(0,11,2))

ax.set_xlabel('X')
ax.set_ylabel('Y')
