Draw Rounded Line Ends Using Matplotlib

To draw rounded line ends using matplotlib, we can use solid_capstyle='round'.

Steps

• Set the figure size and adjust the padding between and around the subplots.
• Create random x and y data points using numpy.
• Create a figure and a set of subplots.
• Plot x and y data points using plot() method, with solid_capstyle in the method argument.
• To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
import numpy as np

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

x = np.random.randn(5)
y = np.random.randn(5)

fig, ax = plt. subplots()
ln, = ax.plot(x, y, lw=10, solid_capstyle='round', color='red')

plt.show()
