有没有办法在dislot上绘制百分比而不是计数?
ax = sns.FacetGrid(telcom, hue='Churn', palette=["teal", "crimson"], size=5, aspect=1)
ax = ax.map(sns.distplot, "tenure", hist=True, kde=False)
ax.fig.suptitle('Tenure distribution in customer churn', y=1, fontsize=16, fontweight='bold');
plt.legend();
seaborn 0.11.2
seaborn.distplot
替换为图形级别seaborn.displot
和轴级seaborn.histplot
,它们有一个stat
参数。使用stat='percent'
。common_bins
和common_norm
进行试验。
common_norm=True
将显示百分比作为整个人口的一部分,而False
将显示相对于组的百分比。import seaborn as sns
import matplotlib.pyplot as ply
# data
data = sns.load_dataset('titanic')
p = sns.displot(data=data, x='age', stat='percent', hue='sex', height=3)
plt.show()
p = sns.displot(data=data, x='age', stat='percent', col='sex', height=3)
plt.show()
labels
中使用的类型批注(:=
)需要python >= 3.8
。可以使用for-loop
实现,而不使用:=
。fg = sns.displot(data=data, x='age', stat='percent', col='sex', height=3.5, aspect=1.25)
for ax in fg.axes.ravel():
# add annotations
for c in ax.containers:
# custom label calculates percent and add an empty string so 0 value bars don't have a number
labels = [f'{w:0.1f}%' if (w := v.get_height()) > 0 else '' for v in c]
ax.bar_label(c, labels=labels, label_type='edge', fontsize=8, rotation=90, padding=2)
ax.margins(y=0.2)
plt.show()
fig = plt.figure(figsize=(4, 3))
p = sns.histplot(data=data, x='age', stat='percent', hue='sex')
plt.show()
common_norm=
参数p = sns.displot(data=data, x='age', stat='percent', hue='sex', height=4, common_norm=False)
p = sns.displot(data=data, x='age', stat='percent', col='sex', height=4, common_norm=False)
fig = plt.figure(figsize=(5, 4))
p = sns.histplot(data=data, x='age', stat='percent', hue='sex', common_norm=False)
plt.show()
