数据集：自杀率，目标：分析数据

（7）自杀率与男女的关系

grouop_data = data.groupby(['Age','Gender'])['SuicidesNo'].sum().unstack()
grouop_data = grouop_data.reset_index().melt(id_vars='Age')
grouop_data_female = grouop_data.iloc[:6,:]
grouop_data_male = grouop_data.iloc[6:,:]

female_=[175437,208823,506233,16997,430036,221984]
male_=[633105,915089,1945908,35267,1228407,431134]
plot_id = 0
for i,age in enumerate(['15-24 years','25-34 years','35-54 years','5-14 years','55-74 years','75+ years']):
    plot_id += 1
    plt.subplot(3,2,plot_id)
    plt.title(age)
    fig,ax = plt.gcf(),plt.gca()
    sns.barplot(x=['female','male'],y=[female_[i],male_[i]])
    plt.tight_layout()#减少堆叠
    fig.set_size_inches(10,15)

grouop_data = data.groupby(['Age','Gender'])['SuicidesNo'].sum()

（8）每个年龄段人口

index_population=[]
for age in data['Age'].unique():
    index_population.append(sum(data[data['Age']==age].Population/len(data[data['Age']==age].Population)))
plt.bar(['15-24 years','35-54 years','75+ years','25-34 years','55-74 years','5-14 years'],index_population,align='center',alpha=0.5)
plt.xticks(rotation=90)
plt.show()

结果：

 

（9）自杀率与年份的关系

sns.set_color_codes('muted')
sns.barplot(x='Year',y='SuicidesNo',data=data,
            label='Year Suicide',color='y')
plt.xticks(rotation=90)
plt.show()

结果：

话说2016发生了什么减少了这么多.....

fig=sns.jointplot(y='SuicidesNo',x='Year',data=data)
plt.show()

结果：

 

fig=sns.jointplot(y='SuicidesNo',x='Population',data=data)
plt.show()

sns.countplot(x='Generation',hue='Gender',data=data)
plt.xticks(rotation=45)
plt.show()
