Plot a multicolored line based on a condition in Python Matplotlib
To plot a multicolored line based on a condition in Python Matplotlib, we can take the following steps −
Set the figure size and adjust the padding between and around the subplots.
Create y data points using numpy.
Make l and u data points to differentiate the colors.
Plot the u and l data points using plot() method, with different colors.
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 y = np.sin(np.linspace(-10, 10, 100)) u = y.copy() l = y.copy() u[u <= 0] = np.nan l[l >= 0] = np.nan plt.plot(u, color='red') plt.plot(l, color='blue') plt.show()
