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.
Example
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
df.plot()
plt.show()Output
