matplotlib去掉边框

一、总结

一句话总结：

去掉上边框：ax.spines['top'].set_visible(False)

fig, ax = plt.subplots()
# 取消边框
for key, spine in ax.spines.items():
    # 'left', 'right', 'bottom', 'top'
    if key == 'left' or key == 'right':
        spine.set_visible(False)

二、matplotlib去掉边框

import numpy as np
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
# 取消边框
for key, spine in ax.spines.items():
    # 'left', 'right', 'bottom', 'top'
    if key == 'left' or key == 'right':
        spine.set_visible(False)
plt.xticks([])
plt.yticks([])
x=[1,2,3,4,5]
y=[4,9,6,8,3]
plt.plot(x,y,'ro')
plt.plot(x,y,'k--')
plt.show()
