回答by Phillip Cloud
You can do this by changing the nameattribute of your subsobject:
您可以通过更改对象的name属性来做到这一点subs：
Assuming its name is 'Settle'and you want to change it to, say, 'Unsettle', just update the nameattribute, like so:
假设它的名称是，'Settle'并且您想将其更改为，例如'Unsettle'，只需更新name属性，如下所示：
In [16]: s = Series(randn(10), name='Settle')
In [17]: s
Out[17]:
0 0.434
1 -0.581
2 -0.263
3 -1.384
4 -0.075
5 -0.956
6 0.166
7 0.138
8 -0.770
9 -2.146
Name: Settle, dtype: float64
In [18]: s.name
Out[18]: 'Settle'
In [19]: s.name = 'Unsettle'
In [20]: s
Out[20]:
0 0.434
1 -0.581
2 -0.263
3 -1.384
4 -0.075
5 -0.956
6 0.166
7 0.138
8 -0.770
9 -2.146
Name: Unsettle, dtype: float64
In [21]: s.name
Out[21]: 'Unsettle'

I finally renamed my Seriesobject to 'Desired_Name' as follows
我终于将我的系列对象重命名为“Desired_Name”，如下所示
# Let my_object be the pandas.Series object
my_object.name = 'Desired_Name'
Then the automatically generated name that now is read in the legend now is 'Desired_Name' against 'Settle' previously.
然后现在在图例中读取的自动生成的名称是“Desired_Name”，而不是以前的“Settle”。

s.reset_index(name="New_Name")
or
或者
s.to_frame("New_Name")["New_Name"]
