setting yticks for yyaxis

Hi!

I am having a problem setting yticks for yyaxis. I am able to set ylable, but yticks is not working. Neither of the below codes work. I get "Array indices must be positive integers or logical values". By changing yticks to start at yticks(1:2:20) I get that the "Index exceeds the number of array elements (11)". I am not sure what is meant with that?

My goal is to show temperature values at the yyaxis right side with same axis length and interval for several plots which has the same temperature, but the yyaxis left is different and therefore it has a different intervall.

yticks(-8:2:12);
yticks([-8 -6 -4 -2 0 2 4 8 10 12]);

You have a variable named yticks that MATLAB thinks you are trying to index.

Thanks a lot! I cleared everything and started over with the yticks comand and now it works. I do not know how I messed that up.
