Hi all,

Have you bump up a problem about "double ytick" when using plotyy?

I got two yticks in the right axis and the second is the one I want. The first yticks belongs to left axis and I want to take it out.

Can you please let me know how to tackle this question?

Thank you!

You could set one axes to have YAxisLocation 'left' and the other
'right', or you could set YTick to the empty array on the one you do not
wish to have any ticks.
