anyway to add grid based on right yyaxis

Hi:

is there anyway to add grid based on right yyaxis instead of the left one?

Thanks!

As Cris LaPierre as already stated the precise algorithm , what you can do is you can just swap the yyaxis right to left and vice versa thereby satisfying your needs .

Or try this example using plotyy() and then follow it to your case:

[AX,H1,H2] =plotyy((1:10),(1:10),(1:10),(1:10).^2);
AX(1).YTick=1:10;  % make sure both the ticks have the same number of points to align them equally
AX(2).YTick=0:10:100;
AX(1).XGrid='on';
AX(2).XGrid='on';
AX(2).YGrid='on';  % grab the second axis handle and add grid lines to it
% AX(1).YMinorGrid='off';
AX(2).LineWidth=2;

Thanks for your reply. I have address the issue by swap the right-left y-axis.

Bests,

Anytime :) , if my answer worked make sure to accept the answer.

[Yu Li]

Yes, your answer works to solve my specific problem. However, it does not provide solution to this topic: 'anyway to add grid based on right yyaxis', so I can not accept it. I'm sorry. I really appreciate your answer.

Bests,

According to the documentation it clearly states that it only works according to left yyaxis so what's the point ? Did you see my second option in the answer? It clearly shows how to add grid to the second y axis.

That function is not recommended after 2016a.

Mathworks has announced 2019 several days ago.

Thank you!

Your welcome! , hopefully the option is added in the latter version.

It does not appear to be possible to add a grid line to the right axis when plotting using yyaxis. There are methods available in Answers if you use plotyy.

My source is the documentation page for yyaxis > Algorithms:

Grid Lines

Grid lines correspond with the tick mark locations along the left y-axis.

Well, then swap your plotting variables so that the variable you want to have aligned grid lines is on the left.

Not being a smart alec, but if you can't beat the system, then use the system.
