- As of seaborn 0.11.2 https://seaborn.pydata.org/whatsnew.html#v0-11-2-august-2021
-
seaborn.distplot https://seaborn.pydata.org/generated/seaborn.distplot.html替换为图形级别seaborn.displot https://seaborn.pydata.org/generated/seaborn.displot.html#seaborn.displot和轴水平seaborn.histplot https://seaborn.pydata.org/generated/seaborn.histplot.html#seaborn.histplot,其中有一个
stat
范围。使用stat='percent'
.
- For both types of plots, experiment with
common_bins
and common_norm
.
- 例如,
common_norm=True
将显示占总人口的百分比,而False
将显示相对于该组的百分比。
- 此中所示的实现answer https://stackoverflow.com/a/68851142/7758804展示如何添加注释。
import seaborn as sns
import matplotlib.pyplot as ply
# data
data = sns.load_dataset('titanic')
图形级别
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()
- 类型注释 (
:=
)用于labels
需要python >= 3.8
。这可以通过以下方式实现:for-loop
,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()
轴水平
fig = plt.figure(figsize=(4, 3))
p = sns.histplot(data=data, x='age', stat='percent', hue='sex')
plt.show()
按组别百分比
- Use the
common_norm=
范围
- See seaborn histplot 和 displot 输出不匹配 https://stackoverflow.com/q/68865538/7758804
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()
