Here we'll create a 2 3 grid of subplots, where all axes in the same row share their y-axis scale, and all axes in the same column share their x-axis scale: In [6]: fig, ax = plt.subplots(2, 3, sharex='col', sharey='row') Note that by specifying sharex and sharey, we've automatically removed inner labels on the grid to make the plot cleaner .
