import numpy as np import matplotlib.pyplot as plt # Data a = np.arange(5) b = [2,4,6,8,10] c = [5, 6, 7, 8, 9] # Create plots fig = plt.figure() ax = plt.subplot() ax.plot(a, b, 'k--', label='Frequency') ax.plot(a, c, 'k:', label='Periods') # Create a legend using the Matplotlib Axes.legend() method in Python. # Set the position using the loc parameter of the legend() method legend = ax.legend(loc='upper center') # Set the background color of the legend using the set_facecolor() function legend.get_frame().set_facecolor('red') # Plot Title plt.title("Frequency of a Signal") # Display plt.show() |
