使用下面的 pdf 页面会生成没有图表的 pdf。
是否可以从数据透视表中解决这个问题?

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

import matplotlib.backends.backend_pdf
pdf = matplotlib.backends.backend_pdf.PdfPages("seaborn.pdf")

# Loop over list 's' for plots
with PdfPages(r'seaborn.pdf') as export_pdf:
    s = ['embark_town', 'class', 'embarked']
    for i in s:
        fig = plt.figure(figsize = [10, 5]);
        ax = titanic.pivot_table(values='fare', columns = i, index='sex', aggfunc='sum').plot()
        export_pdf.savefig(fig, bbox_inches='tight')

用于subplots获取两者figax然后设置 的ax参数DataFrame.plot

import seaborn as sns
from matplotlib import pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages

titanic = sns.load_dataset('titanic')

pdf = PdfPages("seaborn.pdf")

# Loop over list 's' for plots
with PdfPages(r'seaborn.pdf') as export_pdf:
    s = ['embark_town', 'class', 'embarked']
    for i in s:
        fig, ax = plt.subplots(figsize=[10, 5])
        titanic.pivot_table(
            'fare', columns=i, index='sex', aggfunc='sum'
        ).plot(ax=ax)
        export_pdf.savefig(fig, bbox_inches='tight')
