When I import the data into a Jupyter notebook, the numbers in the gdpMillion column become scientific notation.当我将数据导入 Jupyter 笔记本时,gdpMillion 列中的数字变为科学计数法。 How to change them back to normal?
如何让它们恢复正常? And when I draw the line chart, I would like to have the CountryName at the end of each line.
当我绘制折线图时,我希望在每条线的末尾都有 CountryName。
Here is the code of my lineplot这是我的线图的代码
import seaborn as sns
sns.lineplot(x='Year', y='gdpMillion', hue='Country', data=dataset_C,
marker="o", palette="Blues")
sns.despine(left=True, bottom=True)
plt.show()
First, I'll consider that your data is available in a CSV-like file.首先,我会考虑您的数据在类似 CSV 的文件中可用。 My solution includes using the pandas built-in function set_option to account for proper number formating and then using pyplot.text for plotting the names at the end of each line.
我的解决方案包括使用pandas内置 function set_option来说明正确的数字格式,然后使用pyplot.text在每行末尾绘制名称。
I don't think it's the best solution in terms of visualization but, if I understood well what you're looking for, here it goes:我认为这不是可视化方面的最佳解决方案,但是,如果我能很好地理解您在寻找什么,那就是:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
sns.set_style('darkgrid')
pd.set_option('display.float_format', lambda x: '%.3f' % x)
dataset_C = pd.read_csv('dataset_C.csv')
dataset_C['YYYY'] = dataset_C['Year'].apply(pd.to_datetime).apply(lambda x: x.year)
fig, ax = plt.subplots(1,1,figsize=(10,6))
sns.lineplot(x='YYYY',y='gdpMillion',hue='Country', data=dataset_C, marker='o',palette='Blues', ax=ax, legend=False)
for country in dataset_C['Country'].unique():
xpos = dataset_C[dataset_C['Country'] == country].YYYY.max() - 0.2
ypos = dataset_C[dataset_C['Country'] == country].gdpMillion.max() + 100000
plt.text(xpos,ypos,country)
ax.set_xlabel('Year')
Instead, I'd seek for something like:相反,我会寻找类似的东西:
fig, ax = plt.subplots(1,1,figsize=(10,6))
sns.lineplot(x='YYYY',y='gdpMillion',hue='Country', data=dataset_C, marker='o',palette='deep', ax=ax, legend='full')
ax.set_xlabel('Year')
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.)
I hope it helped you.我希望它对你有所帮助。 Regards.
问候。
