Make a multiline plot from .CSV file in matplotlib

To make a multiline plot from .CSV file in matplotlib, we can take the following steps −

  • Set the figure size and adjust the padding between and around the subplots.
  • Create a list of columns to fetch the data from a .CSV file. Make sure the names match with the column names used in the .CSV file.
  • Read the data from the .CSV file.
  • Plot the lines using df.plot() method.
  • To display the figure, use show() method.


import pandas as pd
from matplotlib import pyplot as plt

# Set the figure size
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True

# Make a list of columns
columns = ['mpg', 'displ', 'hp', 'weight']

# Read a CSV file
df = pd.read_csv("auto-mpg.csv", usecols=columns)

# Plot the lines


It will produce the following output
