美元符号 ($) 从 Seaborn FacetGrid 上的 Facet 中删除

Question

我想在 1 个图形上创建 4 个散点图。每个构面都包含带有$ 符号的标题。在 4 个方面中的 2 个方面，$ 符号被删除。有人可以解释为什么以及如何添加$ 符号吗？我还需要从构面标题中删除 Category = 我该怎么做？

下面是复制结果的代码

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

data = {'Price':[1.5,3,10,20],
    'Mcap':[20,30,40,50],
    'Category':['Price <= $2', '$2 < Price <= $5', '$5 < Price <= $15', 
            'Price > $15'],
    'MRR':[20,30,40,50]}

df = pd.DataFrame(data)
print(df)


plot = sns.FacetGrid(df, col="Category", col_wrap=2, height=4,
                    sharey = False)
plot.map(sns.scatterplot, "MRR", "Mcap",alpha=.7)
plt.show()

Answer 1

为转义添加反斜杠并将子图的标题设置为列表。

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

data = {'Price':[1.5,3,10,20],
    'Mcap':[20,30,40,50],
    'Category':['Price <= \$2', '\$2 < Price <= \$5', '\$5 < Price <= \$15', 
            'Price > \$15'],
    'MRR':[20,30,40,50]}

df = pd.DataFrame(data)
print(df)


plot = sns.FacetGrid(df, col="Category", col_wrap=2, height=4,
                    sharey = False)
plot.map(sns.scatterplot, "MRR", "Mcap",alpha=.7)

sub_title = df['Category'].tolist()
for ax, title in zip(plot.axes.flat, sub_title):
    ax.set_title(title)

plt.show()
