Q:

Seaborn boxplot showing number on x-axis, not the name of pd.Series object

Problem : I want my seaborn boxplot to show names of pd.Series(Group A, Group B) 
 on X axis, but it only shows number. The number 0 for the first pd.Series, and 1 for the next pd.Series object.
My codes are as follows.
import pandas as pd
import seaborn as sns

Group_A=pd.Series([26,21,22,26,19,22,26,25,24,21,23,23,18,29,22])
Group_B=pd.Series([18,23,21,20,20,29,20,16,20,26,21,25,17,18,19])

sns.set(style="whitegrid")
ax=sns.boxplot(data=[Group_A, Group_B], palette='Set2')

Result : 

A:

You can concatenate the two series into a dataframe. There are a lot of options to do so, here is one example which will produce nice names:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

Group_A=pd.Series([26,21,22,26,19,22,26,25,24,21,23,23,18,29,22])
Group_B=pd.Series([18,23,21,20,20,29,20,16,20,26,21,25,17,18,19])
df = pd.DataFrame({"ColumnA" : Group_A, "ColumnB" : Group_B})

sns.set(style="whitegrid")
ax=sns.boxplot(data=df , palette='Set2')

plt.show()
