如何绘制带有分类轴和数字（基准）轴的折线图？

Question

Seaborn enables you to create a categorical plot using points

import seaborn as sns

tips = sns.load_dataste('tips')
sns.catplot(x='tip', y='sex', data=tips, jitter=False)

Is there a way to connect the points with a line for the same gender?

My goal is to create a plot that will be similar to the below figure (done in R's ggplot2 ). Reading the seaborn documentation I find nothing that would resemble this plot. The lineplot only takes in numeric values. Is currently there an obvious way to make this categorical plot this that I'm missing?

Answer 1

Group by the category and plot each line individually.

import numpy as np
import matplotlib.pyplot as plt

def cat_horizontal_plot(data, category, numeric, ax=None):
    ax = ax or plt.gca()
    for cat, num in data.groupby(category):
        ax.plot(np.sort(num[numeric].values), [cat]*len(num),
                marker="o", mec="k", mfc="none", linestyle="-", color="k")
    ax.set_xlabel(numeric)
    ax.set_ylabel(category)
    ax.margins(y=0.4)
    ax.figure.tight_layout()

Use it as

import seaborn as sns
tips = sns.load_dataset('tips')

cat_horizontal_plot(tips, "sex", "tip")
plt.show()
