將空字符串傳遞給matplotlib的yticks

This webpage已經讓我相信我可以傳遞一個空字符串到matplotlib.yticks以關閉圖形的y-ticks。將空字符串傳遞給matplotlib的yticks

然而，當我試圖做到這一點，我得到以下錯誤：

In [1]: from pylab import * 

In [2]: figure() 
Out[2]: <matplotlib.figure.Figure at 0xb69d43cc> 

In [3]: yticks('')

    1298   if len(self.majorTicks) < numticks: 
    1299    # update the new tick label properties from the old 

TypeError: len() of unsized object

這是怎麼回事？如果這種關閉y-ticks的方法不正確，那麼正確的方法是什麼？

的yticks從matplotlib函數期望列表作爲參數而不是字符串。因此，關閉的y蜱，

In [1]: import matplotlib.pyplot as plt 
In [2]: plt.figure() 
Out[2]: <matplotlib.figure.Figure at 0x10ef23710> 

In [3]: plt.yticks([]) 
Out[3]: ([], <a list of 0 Text yticklabel objects>)

在過去在matplotlib蜱更多的控制，可考慮使用tick_params如this answer指出。

這個問題的可接受的解決方案應該實現你想要的，並讓你更好地控制顯示內容。

Remove xticks in a matplot lib plot?

例如，用於關閉所有蜱在y軸：

>>> from pylab import * 
>>> figure() 
>>> plot(arange(10)) 
>>> tick_params(axis='y', which='both', left='off', right='off', labelleft='off') 
>>> show()

很酷，謝謝。正在傳遞一個空字符串，這個字符串曾經被支持但不再是？ – dbliss
