的Python matplotlib ValueError異常的羅吉特規模軸標籤

我得到使用matplotlib設置一個羅吉特規模軸的標籤時是什麼樣子的標籤定位誤差，這是我的例子：的Python matplotlib ValueError異常的羅吉特規模軸標籤

import matplotlib.pyplot as plt; 
from matplotlib.ticker import FormatStrFormatter; 

x = [1,2,3,4,5]; 
y = [0.1,0.2,0.3,0.4,0.5]; 

fig,ax = plt.subplots(); 

ax.set_ylim([0.005,0.99]); 
ax.set_yscale('logit'); 
ax.yaxis.set_minor_formatter(FormatStrFormatter("")); 

ax.set_xlabel("X axis"); 
ax.set_ylabel("Y axis"); #set y axis label (logit scale) 

ax.plot(x,y); 
plt.show(); 
plt.close();

這裏的痕跡：

ValueError: posx and posy should be finite values

偉大的作品時，我省略

ax.set_ylabel("Y axis"); #set y axis label (logit scale)

這似乎並不重要的升abel在軸比例之前或之後設置。任何人都知道如何解決這個問題？

設置文本標籤的方式存在一個錯誤，這會導致Logit比例的非數字邊界框，請參見this issue on GitHub。

的解決方案是增加

ax.spines['left']._adjust_location()

（其中'left'可以通過'right'，'top'，'bottom'根據軸來代替一個有興趣）中的代碼。

完整的示例：

import matplotlib.pyplot as plt 

x = [1,2,3,4,5] 
y = [0.05,0.2,0.3,0.4,0.95] 

fig,ax = plt.subplots() 

ax.set_yscale('logit') 

ax.set_xlabel("X axis") 
ax.set_ylabel("Y axis") 
ax.spines['left']._adjust_location() 

ax.plot(x,y) 
plt.show()
