Matplotlib: TypeError: 'AxesSubplot' 对象不可下标 [英] Matplotlib: TypeError: 'AxesSubplot' object is not subscriptable

问题描述

我正在尝试对包含在两个数据帧df1和df2中的变量'x'进行简单的箱形图绘制.为此，我使用以下代码:

I am trying to make a simple box plot of a variable 'x' contained in two dataframes, df1 and df2. To do this I am using the following code:

fig, axs = plt.subplots()
axs[0, 0].boxplot([df1['x'], df2['x']])
plt.show();

但是，我明白了:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-108-ce962754d553> in <module>()
----> 2 axs[0, 0].boxplot([df1['x'], df2['x']])
      3 plt.show();
      4 

TypeError: 'AxesSubplot' object is not subscriptable

有什么想法吗?

推荐答案

fig, axs = plt.subplots()

返回仅包含一个子图的图形，因此斧头已经拥有该图形而无需编制索引.

returns a figure with only one single subplot, so axs already holds it without indexing.

fig, axs = plt.subplots(3)

返回子图的一维数组.

fig, axs = plt.subplots(3, 2)

返回子图的二维数组.

请注意，这只是由于 kwarg 的默认设置 squeeze=True.
通过将其设置为 False ，您可以强制结果为2D数组，而与子图的数量或排列方式无关.

Note that this is only due to the default setting of the kwarg squeeze=True.
By setting it to False you can force the result to be a 2D-array, independant of the number or arrangement of the subplots.
