In the pandas Python library, we can use the DataFrame.plot.line() function to plot a line plot. The x parameter indicates the values on the x-axis and the y parameter indicates the values on the y-axis.

Let’s read the “flights” dataset. The dataset contains various information, such as year, number of passengers, etc. Let’s say we want to see a line plot between the number of passengers and the year. We can use the following Python code for that purpose:

import pandas
from matplotlib import pyplot

df = pandas.read_csv("flights.csv")
df.plot.line(x="year", y="passengers")
pyplot.savefig("flights-line.png")

Here, the DataFrame.plot.line() function plots a line plot. The x-axis indicates the years and the y-axis indicates the number of passengers.

The resulting line plot looks like the following:

Please note that when we do not specify the x parameter in the DataFrame.plot.line() function, the …
