I have made a subplot in matplotlib and managed to to put the different cmap I have on the same column. For a minimal working example (without the cmaps):

fig_bandwidth = plt.figure(figsize=(12, 6))
    ax1 = plt.subplot(3, 2, 6)
    ax2 = plt.subplot(3, 2, 4)
    ax3 = plt.subplot(3, 2, 2)
    ax_bandwidth = plt.subplot(1, 3, 1)
    axes = [ax1, ax2, ax3]
for ax in axes:
    ax.axis('off')

What I am trying to do is have a tight subplot with the figure on the left and the 3 color bars on the right in the same column, but it seems the plotting boxes are still there, preventing me from placing these axes next to the figure. Maybe using subplots isn’t the best solution, any suggestion?
