python - 隐藏图中的 y 轴

Question

简单问题:我需要从这段代码生成的图中隐藏 y 轴:

import matplotlib.pyplot as plt
import seaborn
seaborn.set(style="white")
import random

objects = [("Zachary's karate club", 78),
            ("dolphins social network", 159),
            ("C. elegans connectome", 2148 ),
            ("US power grid", 6594 ),
            ("PGP web of trust (2004)", 24316),
            ("Linux kernel source file includes", 230213),
            ("Enron emails (1999-2003)", 1148072),
            ("Internet autonomous systems (2005)", 11095298),
            ("CS collaborations (DBLP)", 18e6),
            ("Wikipedia hyperlinks", 350e6),
            ("Twitter follower graph (2012)", 20e9),
            ("Facebook social graph (2011)", 68.7e9),
            ("NSA social graph (?)", 1e11),
            ("human connectome (neuronal)", 1e14)
           ]

fig, ax = plt.subplots(figsize=(16,6))

for i, (name, radius) in enumerate(objects):
    sgn = 2 * (i % 2) - 1
    ax.annotate(name, xy=(radius,0), xytext=(radius,sgn* (0.5 + random.randint(1,12) * 0.1)), ha='center',
                arrowprops=dict(arrowstyle="->", connectionstyle="arc,angleA=0,armA=30,rad=30", facecolor='gray'),
               color="Maroon")
ax.set_xscale('log')
ax.set_xlim(1.e1,1.e15)
ax.set_ylim(0,4)
ax.axes.get_yaxis().set_visible(False)
ax.axhline(color='k', lw=1)
ax.plot([obj[1] for obj in objects], [0]*len(objects), 'ob', markersize=2)
ax.set_yticks([])
ax.tick_params(length=8)
ax.set_xlabel('edges')
seaborn.despine()
plt.show()

应该很简单，但是到目前为止我找到的所有代码示例都没有用，例如fig.axes[0].get_yaxis().set_visible(False)

左轴来自seaborn ，不是 matplotlib。您可以使用以下方法将其关闭:

seaborn.despine(left=True)

下面是对 tcaswell 评论的回应:

Seaborn 向绘图添加样条。 despine 命令接受以下参数来删除它们。但是，您必须明确告诉它关闭左侧或底部。

seaborn.despine(fig=None, ax=None, top=True, right=True, left=False, bottom=False, offset=None, trim=False)

其中

top, right, left, bottom : boolean, optional
If True, remove that spine.
