Matplotlib : matplotlibrc ( 1) , , Python. If you know the bottom and top kwargs that went into a GridSpec initialization, or you otherwise know the edges positions of your axes in Figure coordinates, you can also specify the ylabel position in Figure coordinates with some fancy "transform" magic. Due to simplicity this should be the accepted answer. If you add the plt.tight_layout() statement to the end of this code block, this problem resolves itself.
