How to avoid the extra set of y-axis labels?

[deanhystad]

twinx() creates a new axis. Your code creates two many new axis because you call twinx() multiple times. You should do something like this:

y2 = axs[0].twinx()
y2.set_ylabel('SPX Price')

I like the "Plots with different scales" example shown here
