To change the spacing of dashes in a dashed line in matplotlib, we can take the following steps −
Create data points x and y using numpy.
Initialize two variables space and dash_len with value 3.
Plot x and y using plot() method, with line style '--', dashes tuple stores the property of dashed line.
To display the figure, use show() method.
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-1, 1, 100) y = np.sin(x) space = 3 dash_len = 3 plt.plot(x, y, c='red', linestyle='--', dashes=(dash_len, space), lw=5) plt.show()
