Python code for vertical barcode

import matplotlib.pyplot as plt
import numpy as np

# the bar
x = np.random.rand(500) > 0.7

fig = plt.figure()

# a Verticle Barcode
ax = fig.add_axes([0.1, 0.2, 0.1, 0.8])
ax.set_axis_off()
ax.imshow(x.reshape((-1, 1)), aspect='auto', 
          cmap='binary', interpolation='nearest')
ax.set_title('Verticle Barcode Example 1')
plt.show()
