我有一个随机森林特征重要性程序。已为每个变量生成所有特征重要性参数。我还将其绘制在水平条形图上。

现在我想将条形按升序/降序排序。我该怎么做？

我的代码如下：

#Feature Selection (shortlisting key variables)

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

from sklearn.metrics import mean_squared_error
from sklearn.model_selection import train_test_split

from sklearn.ensemble import RandomForestRegressor
from sklearn.ensemble import RandomForestClassifier
from sklearn.feature_selection import SelectFromModel
from sklearn.metrics import accuracy_score

df = pd.read_excel(r'C:\Users\z003v0ee\Desktop\TP Course\project module\ProjectDataSetrev4.xlsx',sheet_name=0)
df2 = pd.read_excel(r'C:\Users\z003v0ee\Desktop\TP Course\project module\ProjectDataSetrev4.xlsx',sheet_name=1)

## Convert date time format and set as index
df['DateTime']=pd.to_datetime(df['Time Stamp'], format='%Y-%m-%d %H:%M:%S')
df.set_index(df['DateTime'], inplace=True)

## Save each feature to a list (independent variables)
allvarlist = …
