您可以更换g.figure
with g.fig
. g.figure
旨在成为同一变量的新名称。refline()
是seaborn 0.11.2 中的新增内容(该网站假设您运行最后发布的版本)。您可以将呼叫替换为g.refline()
with g.map(plt.axhline, y=0, linewidth=2, linestyle="-", color=None, clip_on=False)
.
import numpy as np
import pandas as pd
import seaborn as sns

这是使用航班数据集的另一个示例:
import numpy as np
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
sns.set_theme(style="white", rc={"axes.facecolor": (0, 0, 0, 0)})
flights = sns.load_dataset('flights')
pal = sns.cubehelix_palette(len(flights["year"].unique()), start=1.4, rot=-.25, light=.7, dark=.4)
g = sns.FacetGrid(flights, row="year", hue="year", aspect=20, height=.5, palette=pal)
g.map(sns.kdeplot, "passengers", bw_adjust=.6, cut=5, clip_on=False, fill=True, alpha=1, linewidth=1.5)
g.map(sns.kdeplot, "passengers", bw_adjust=.6, cut=5, clip_on=False, color="w", lw=2)
g.map(plt.axhline, y=0, linewidth=2, linestyle="-", color=None, clip_on=False)
def label(x, color, label):
ax = plt.gca()
ax.text(0, .1, label, fontweight="bold", color=color,
ha="left", va="center", transform=ax.transAxes)
g.map(label, "year")
g.fig.subplots_adjust(hspace=-.7)
g.set(yticks=[], xlabel="", ylabel="", xlim=(None, 680), title="")
g.despine(bottom=True, left=True)
plt.show()
