我需要帮助添加标记或符号的平均值在这个图如图所示.(下面的图片显示了我想要的结果.
import pandas as pd
import seaborn as sns
import numpy as np
import matplotlib.pyplot as plt
import plotly.express as px
data = pd.DataFrame({'job_title':np.random.choice(['data_science','Data_analysis'],400),
'experience_level':np.random.choice(['entry','senior'],400),
'salary':np.random.choice((50000),400)})
data.head(1)
data= data.sort_values(by='experience_level', ascending=True)
fig = px.strip(data, x='job_title', y='salary', color='experience_level')
fig.update_layout(width=800, height=600)
fig.show()
