matplotlib制作雷达图报错ValueError的实现

import numpy as np
import matplotlib.pyplot as plt
import matplotlib
matplotlib.rcParams['font.family']='SimHei'
matplotlib.rcParams['font.sans-serif'] = ['SimHei']
labels = np.array(['综合','KDA','发育','推进','生存','输出'])
nAttr = 6
data = np.array([7,5,6,9,8,7])
angles = np.linspace(0,2*np.pi,nAttr,endpoint=False)
data = np.concatenate((data,[data[0]]))
angles = np.concatenate((angles,[angles[0]]))
fig = plt.figure(facecolor="white")
plt.subplot(111,polar=True)
plt.plot(angles,data,'bo-',color ='g',linewidth=2)
plt.fill(angles,data,facecolor='g',alpha=0.25)
plt.thetagrids(angles*180/np.pi,labels)
plt.figtext(0.52,0.95,'DOTA能力值雷达图',ha='center')
plt.grid(True)
plt.show()

data = np.concatenate((data,[data[0]]))
angles = np.concatenate((angles,[angles[0]]))
labels=np.concatenate((labels,[labels[0]]))  #对labels进行封闭
