Why is ax2 writing over ax1's y-axis in matplotlib subplots?

Question

I am trying to change the code I had which was a twinx chart before into subplots. I'm unfamiliar with subplots and haven't been able to figure out why ax2 labels are writing over ax1's y axis labels.

The goal is to get the labels in ax2 to the right.

When I run the code with the label:

When I remove the label:

Answer 1

Try this:

ax2.yaxis.set_label_position('right')
ax2.yaxis.tick_right()

just after (ax1, ax2) = axs
