Python Line Charts

Legends are especially useful when dealing with multiple time series in a chart — here’s how to move the default legend to the bottom right:

Code:

import pandas as pd

df = pd.read_excel('world_population_growth.xlsx')

df.plot( 'Year' , 'Population' )

plt.xlabel('Year')

plt.ylabel('Population (billions)')

plt.title('World Population Growth By Year', fontsize=18, color="blue", pad = 10, loc="left", fontstyle='italic')

plt.legend(loc="lower right")

Explanation:

Loc specifies where in the chart you’d like to place the legend, and the visual customizations we’ve added in the title and x and y labels in previous lessons are also available too.
