Code for reproduction

import matplotlib.pyplot as plt
import numpy as np

N = 18
state = np.random.RandomState(51423)
data = 1e5 * np.cumsum(state.rand(N, N), axis=0)
fig, ax = plt.subplots()
m = ax.pcolor(data)
fig.colorbar(m, ax=ax, extend='max', location='right')
fig.colorbar(m, ax=ax, extend='max', location='left')
