用jupyter来统计数据，画出柱状图
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import matplotlib %matplotlib inline
matplotlib.rcParams['font.sans-serif'] = ['SimHei']
data = pd.read_csv('tips.csv')
result = data['sex'].value_counts()
# result.plot(kind='bar',color=['red','blue']) people_count = [,,,,]
plt.figure() #出事化一个画布
plt.subplot(,,) #绘制位置
plt.bar(range(),height=people_count,color=['red','pink','blue','green','red'])
plt.xticks(range(),['A','B','C','D','E'])
plt.xlabel('专业名称')
plt.ylabel('数量')
plt.title('专业信息')
plt.plot(people_count,color='red') #线图 plt.subplot(,,)
plt.pie(people_count,labels=['A','B','C','D','E'],autopct='%1.1f%%')
