python - seaborn: share X label not working as expected

Question

i am dealing with a dataset that shows relationships between two points, such as bus stops. For example, we have bus stops A, B, C, and D.

I want to make histogram p

Answer 1

As seen from the documentation, sns.boxplot has an argumen order

order, hue_order : lists of strings, optional
Order to plot the categorical levels in, otherwise the levels are inferred from the data objects.

Using this like

sns.boxplot(..., order=['A','B','C','D'])

would give you the desired plot.

Complete code:

import pandas as pd
import numpy as np
import seaborn as sns
import matplotlib.pyplot as plt

time=np.random.randn(1000)
point1 = ['A','B','C','D'] * 250
point2 = ['A'] * 250 + ['B'] * 250 + ['C'] * 250 + ['D'] * 250 

df_time = pd.DataFrame(
    {'point1': point1,
     'point2': point2,
     'time': time
    })
df_time=df_time[df_time['point1']!=df_time['point2']] ##cannot sell to another

fig, ax = plt.subplots(nrows=4, sharey=True)

for point1i, axi in zip(point1, ax.ravel()):
    sns.boxplot(data=df_time[df_time['point1']==point1i], x='point2', y='time', 
                ax=axi, order=['A','B','C','D'])

plt.tight_layout()    
plt.show()
