仅显示列值而不是 column_name = catplot 子图标题中的列值

Question

我正在尝试生成不同的箱线图，这些箱线图描述了某些产品系列和行业组（“生产”、“贸易”、“商业”、“休闲与健康”）的变量分布。

我想知道：

如果有办法在子图标题中只显示“生产”、“贸易”、“商业”和“休闲与健康”，而不是每次都显示“industry_group = 生产”等等在
如果有办法将这些子图的标题从每个子图的上边框提高一点（在我发布的图像中你可以清楚地看到它们没有 space）

在我正在使用的代码下方，这里有一张图片向您展示我得到的结果 --> Catplot Image。

import matplotlib.pyplot as plt
import seaborn as sns

sns.set_context("talk")

boxplot = sns.catplot(
    x='family', 
    y='lag',
    hue="SF_type",
    col="industry_group",
    data=df1, 
    kind="box",
    orient="v",
    height=8, 
    aspect=2,
    col_wrap=1,
    order=fam_sort,
    palette='Set3',
    notch=True,
    legend=True,
    legend_out=True,
    showfliers=False,
    showmeans=True,
    meanprops={
        "marker":"o",
        "markerfacecolor":"white", 
        "markeredgecolor":"black",
        "markersize":"10"
    }
)

boxplot.fig.suptitle("Boxplots by Product Basket, Industry Group & SF Type", y=1.14)

#repeat xticks for each plot
for ax in boxplot.axes:
    plt.setp(ax.get_xticklabels(), visible=True, rotation=75)
    plt.subplots_adjust(hspace=1.2, top = 1.1)
    
#remove axis titles
for ax in boxplot.axes.flatten():
    ax.set_ylabel('')
    ax.set_xlabel('')
    limit_upper = max(df1.groupby(['family','SF_type','industry_group'])['lag'].quantile(0.75))
    plt.setp(ax.texts, text="")
    ax.set(ylim=(-10, limit_upper ))

可以用set_titles()改变。 {} 指定要绘制子图的列或行。详见docstring，seaborn官方参考中的例子修改字幕。

Signature: g.set_titles(template=None, row_template=None, col_template=None, **kwargs) Docstring: Draw titles either above each facet or on the grid margins.

Parameters template : string Template for all titles with the formatting keys {col_var} and {col_name} (if using a col faceting variable) and/or {row_var} and {row_name} (if using a row faceting variable). row_template: Template for the row variable when titles are drawn on the grid margins. Must have {row_var} and {row_name} formatting keys. col_template: Template for the row variable when titles are drawn on the grid margins. Must have {col_var} and {col_name} formatting keys.

import seaborn as sns
sns.set_theme(style="ticks")

titanic = sns.load_dataset("titanic")

g = sns.catplot(x="embark_town", y="age",
                hue="sex", row="class",
                data=titanic[titanic.embark_town.notnull()],
                height=2, aspect=3, palette="Set3",
                kind="violin", dodge=True, cut=0, bw=.2)
g.set_titles(template='{row_name}')

默认：

仅显示列值而不是 column_name = catplot 子图标题中的列值

Show only column value instead of column_name = column value in catplot subplots titles

python

seaborn
