To plot a dashed line on a Seaborn lineplot, we can use linestyle="dashed" in the argument of lineplot().
Steps
Set the figure size and adjust the padding between and around the subplots.
Create x and y data points using numpy.
Use lineplot() method with x and y data points in the argument and linestyle="dashed".
To display the figure, use show() method.
Example
import seaborn as sns import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.random.rand(10) y = np.random.rand(10) ax = sns.lineplot(x=x, y=y, linestyle="dashed") plt.show()
