fig.suptitle('matplotlib.figure.Figure.clear() \
function Example\n\n', fontweight ="bold")

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
    
t = np.linspace(0.0, 2.0, 201)
s = np.sin(2 * np.pi * t)
 
fig, [ax, ax1] = plt.subplots(2, 1, 
                              sharex = True)
 
ax.set_ylabel('y-axis')
ax.plot(t, s)
ax.grid(True)
ax.set_title('Sample Example',
             fontsize = 12,
             fontweight ='bold')
 
ax1.set_ylabel('y-axis')
ax1.plot(t, s)
ax1.grid(True)

fig.clear(False)
