问题描述
我试图从 17001 行 × 6 列的 DataFrame 绘制预期寿命 life_expect['CountryName'] 超过 80 岁的国家 life_expect['Value'] 。
处理和绘图所需的时间超过 30 分钟。我做错了什么，如何使代码更快？
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
from scipy import stats
indicators = pd.read_csv('Indicators.csv')
year = indicators['Year']
hist_indicator = indicators['IndicatorName'].str.contains('Life expectancy at birth')
le = indicators[year & hist_indicator]
x = le[~le['CountryName'].str.contains('OECD')]
x = x[~x['CountryName'].str.contains('income')]
x = x[~x['CountryName'].str.contains('Euro')]
life_expect = x
highest_life_expect = life_expect[life_expect['Value'] > 80]
sns.set_style("darkgrid")
sns.catplot(x = 'CountryName',y = 'Value',hue = 'Year',row='IndicatorName',data = highest_life_expect,palette = 'YlOrBr',kind = 'strip',dodge = True,height = 1.5,aspect=3)
plt.xticks(rotation= 70)
plt.show()
数据帧示例：
life_expect = pd.DataFrame({'CountryName': {23215: 'arab World',23216: 'arab World',23217: 'arab World',23311: 'Caribbean small states',23312: 'Caribbean small states',23313: 'Caribbean small states',23657: 'East Asia & Pacific (developing only)',23658: 'East Asia & Pacific (developing only)',23659: 'East Asia & Pacific (developing only)',24249: 'Fragile and conflict affected situations'},'CountryCode': {23215: 'ARB',23216: 'ARB',23217: 'ARB',23311: 'CSS',23312: 'CSS',23313:
