fig = plt.figure()
ax1 = fig.add_subplot(111, projection='3d')

xpos = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]
ypos = [2,3,4,5,1,6,2,1,7,2,3,5,1,3,2]
num_elements = len(xpos)
zpos = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]

dy = np.ones(15)
dz = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]

ax1.bar3d(xpos, ypos, zpos, dx, dy, dz, color='#00ceaa')
plt.show()
