所以我想从csv数据文件中生成一个图表图表,并且我一直在关注指南,但我似乎无法以这样的方式操纵我的代码以获得我想要的东西。< / p>
所以这就是我到目前为止:
from pandas import DataFrame, read_csv
import matplotlib.pyplot as plt
import pandas as pd
import sys
import matplotlib
df = pd.read_csv("TB_burden_countries_2018-03-06.csv")
df = df.set_index(['country'])
df2 = df.loc["Zimbabwe", "e_mort_num"]
df2 = df.loc["Zimbabwe", "e_mort_num"]
df = pd.DataFrame(data = df2, columns= ["e_mort_num"])
df.columns = ["Mortality"]
print(df2)
这段代码就是这样我可以选择一个特定国家(津巴布韦)并查看其人口编号(e_mort_num)。我可以写什么来生成图表图表?我一直在使用本教程:http://pbpython.com/simple-graphing-pandas.html,但我在操作变量名称方面遇到了麻烦,我不太清楚我应该做什么。如果您需要更多信息,请说明。谢谢你的帮助!
感兴趣的CSV位:
Country Year Mortality
Zimbabwe 2000 20000
Zimbabwe 2001 18000
Zimbabwe 2002 17000
Zimbabwe 2003 19000
Zimbabwe 2004 19000
Zimbabwe 2005 22000
Zimbabwe 2006 24000
Zimbabwe 2007 24000
Zimbabwe 2008 23000
Zimbabwe 2009 17000
Zimbabwe 2010 13000
Zimbabwe 2011 14000
Zimbabwe 2012 14000
Zimbabwe 2013 11000
Zimbabwe 2014 11000
Zimbabwe 2015 9000
Zimbabwe 2016 5600
答案 0 :(得分:1)
假设您的数据框如下所示:
>>> df
Country Year Mortality
0 Zimbabwe 2000 20000
1 Zimbabwe 2001 18000
2 Zimbabwe 2002 17000
3 Zimbabwe 2003 19000
4 Zimbabwe 2004 19000
5 Zimbabwe 2005 22000
6 Zimbabwe 2006 24000
7 Zimbabwe 2007 24000
8 Zimbabwe 2008 23000
9 Zimbabwe 2009 17000
10 Zimbabwe 2010 13000
11 Zimbabwe 2011 14000
12 Zimbabwe 2012 14000
13 Zimbabwe 2013 11000
14 Zimbabwe 2014 11000
15 Zimbabwe 2015 9000
16 Zimbabwe 2016 5600
您可以使用以下代码获取条形图:
# Plot mortality per year:
plt.bar(df['Year'], df['Mortality'])
# Set plot title
plt.title('Zimbabwe')
# Set the "xticks", for barplots, this is the labels on your x axis
plt.xticks(df['Year'], rotation=90)
# Set the name of the x axis
plt.xlabel('Year')
# Set the name of the y axis
plt.ylabel('Mortality')
# tight_layout makes it nicer for reading and saving
plt.tight_layout()
# Show your plot
plt.show()
这给了你:
