柱状图

import numpy as np

import pandas as pd

from pandas import Series

titanic = pd.read_csv("E:/Anaconda/MachineLearningData/Titanic/test.csv")

titanic_age = titanic["Age"]

age_is_null = titanic_age.isnull()

avaliable_age = titanic_age[age_is_null==False]

avaliable_titanic = titanic[age_is_null==False]

avaliable_name = avaliable_titanic["Name"]

bar_height = avaliable_age[0:5].values       #设置y轴值

bar_position = avaliable_name[0:5].values      #设置x轴值

fig = plt.figure(figsize=(15,12))

plt.bar(bar_position,bar_height,0.7)      #第三个参数为柱体的宽度

#plt.barh(bar_height,bar_position,0.7)  #这个函数可以画出来横着的柱形图

plt.xlabel("Name")

plt.ylabel("Age")

plt.title("Age of person in Titanic")

plt.plot()
