How to plot a gradient color line in matplotlib?

To plot a gradient color line in matplotlib, we can take the following steps −

• Create x, y and c data points, using numpy.

• Create scatter points over the axes (closely so as to get a line), using the scatter() method with c and marker='_'.

• To display the figure, use the show() method.

Example

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.linspace(-1, 1, 1000) y = np.exp(x) c = np.tan(x) plt.scatter(x, y, c=c, marker='_') plt.show()
