AttributeError：'numpy.ndarray'對象沒有屬性'值'使用PANDAS

Question

嗨我想在數據示例上使用bootstrap_plot（）函數，但遇到以下錯誤。我已經使用相同的數據數組使用matplotlibs hist（）函數繪製直方圖，沒有任何問題。

Traceback (most recent call last): 
File "/home/Astrophysics/BootStrapping.py", line 19, in <module> 
    bootstrap_plot(C, size=17517, samples=1000, color='grey') 
    File "/usr/local/lib/python2.7/dist-packages/pandas-0.8.2.dev_eec8a83-py2.7- linux- i686.egg/pandas/tools/plotting.py", line 301, in bootstrap_plot 
    data = series.values 
AttributeError: 'numpy.ndarray' object has no attribute 'values' 

我的代碼

import matplotlib.pyplot as plt 
import numpy as np 
import scipy 
import matplotlib.mlab as mlab 
import statsmodels.api as sm 
import pyfits 
from pandas.tools.plotting import bootstrap_plot 

F = '/home/khary/Astrophysics/outfiles/outmag20_2dr_9_658.txt' 
#data_cube ,header_data_cube = pyfits.getdata("/home/Astrophysics/SDSS_Counts /count.dr72bright0.3dlz01r01c06.0.fits",1,header=True) 


#load arrays with data 
data=np.loadtxt(F) 
C=data[:,3] 
#obs_count = data_cube.field(3) 

#Bootstrap plot 
bootstrap_plot(C, size=17517, samples=1000, color='grey') 
plt.show()

大熊貓bootstrap_plot需要一個系列的第一個參數。

from pandas import Series 
bootstrap_plot(Series(C), size=17517, samples=1000, color='grey')
