I have 9 matplotlib subplots arranged in a grid. I'm trying to do two simple things: (1) adjust subplot spacing to reduce white space, (2) place the legend outside of the plot. Individually, both things are super easy. Together, they don't work: If I place legend outside of the subplots using bbox_to_achnor=(...), subplot spacing gets messed up and subplots_adjust(...) don't work anymore.

UPD: This works for tight spacing:

fig, axes = plt.subplots(3, 3)

plt.subplot(331)
# plot something on every subplot
plt.subplot(339)
# plot something here too

plt.subplots_adjust(wspace=0, hspace=0)
plt.tight_layout()
plt.savefig("blabla.pdf", format="pdf")

And with this code all figures become squeezed:

fig, axes = plt.subplots(3, 3)

plt.subplot(331)
# plot something on every subplot
plt.subplot(339)
# plot something here too

# add outside legend to the first plot
plt.subplot(331)
lgd = plt.legend(ncol=1, loc=2, prop='size': 10, bbox_to_anchor=4.2, 0.2))

plt.subplots_adjust(wspace=0, hspace=0)
plt.tight_layout()
plt.savefig("blabla.pdf", format="pdf", bbox_inches="tight", bbox_extra_artists=(lgd,))

Any ideas?

Things will supposedly work fine if you use the legend with the figure object fig. Currently you use it with the last plt object which correspond to the last subfigure 339. Using fig, you don't need a large offset of 4.2 for the bbox_to_anchor. Something like 1.1 or 1.2 should work fine

lgd = fig.legend(ncol=1, loc=2, prop='size': 10, bbox_to_anchor=(1.2, 0.2))

  Thanks a lot for the advice! The trick worked for me. I'm having hard time to understand why this "squeeze" effect occur though.
