python Seaborn - annotations with pointplot

问题

I am using a pointplot in seaborn.

import seaborn as sns
sns.set_style("darkgrid")
tips = sns.load_dataset("tips")
ax = sns.pointplot(x="time", y="total_bill", hue="smoker",data=tips)

I would like to annotate all of the points. If there are points in between, I would like to label the points in between along with the line ends if that makes sense.

Thank you so much!

The question is rather unspecific, but here is how to label each point in a pointplot, just as you would do with any other matplotlib scatter plot:

import matplotlib.pyplot as plt
import seaborn as sns

tips = sns.load_dataset("tips")
ax = sns.pointplot(x="time", y="total_bill", hue="smoker", data=tips)

for c in ax.collections:
    for of in c.get_offsets():
        ax.annotate("Label", of)

plt.show()
