Вы можете использовать ImageGrid , который был разработан, чтобы упростить такие вещи
data = np.vstack([
np.random.multivariate_normal([10, 10], [[3, 2], [2, 3]], size=100000),
np.random.multivariate_normal([30, 20], [[2, 3], [1, 3]], size=1000)
])
from mpl_toolkits.axes_grid1 import ImageGrid
fig = plt.figure(figsize=(4, 6))
grid = ImageGrid(fig, 111, # similar to subplot(111)
nrows_ncols=(3, 2), # creates 2x2 grid of axes
axes_pad=0.1, # pad between axes in inch.
cbar_mode="single",
cbar_location="right",
cbar_pad=0.1
)
for ax in grid:
h = ax.hist2d(data[:, 0], data[:, 1], bins=100)
fig.colorbar(h[3], cax=grid.cbar_axes[0], orientation='vertical')
