这是一个带有随机块的简短示例，以帮助说明问题。这将适用于您的数据。
a.select(lambda row: (row[0] == 'a' and row[1] == 'x0') or (row[0] == 'b' and row[1] == 'x1'))
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline
#creating random block
data = {'a' : np.random.randint(0, 10, size = 10),
'b' : np.random.randint(0, 10, size = 10),
'c' : np.random.randint(0, 10, size = 10),
'd' : np.random.randint(0, 10, size = 10),
'e' : np.random.randint(0, 10, size = 10)}
df = pd.DataFrame(data)
#what is happening
df.plot()
