KDE图的Seaborn加权平均线

Question

有人知道如何将参考线图添加到表示每个x值中位数的kdeplot中。

我尝试通过使用汉明滤镜进行卷积来使其平滑，但效果并不理想。

Answer 1

最后，我通过绘图解决了

# create an aggregation ef
ef = df[['Temp','Power]].groupby('Temp').median().reset_index()

# smooth the aggregation with mean() - shift(- half window) is needed for alignment
ef['roll_med_power'] = ef['Power'].rolling(5).mean().shift(-2)

# finally close the gaps at beginning and end with unsmoothed data
ef['roll_med'][:2] = ef['Power'][:2]
ef['roll_med'][-2:] = ef['Power'][-2:]
