I plotted a figure with two y-axis with different y limit
But I would like to limit the yyaxis of the right axis so that right axis starts with the lower limit of the left plot and upper limit of the right plot?
Or if it is possible that the zero-axis of both plots matches?
I manually shifted the right plotted axis so that the zeros matches for both axis.
I have already checked the following discussion: https://de.mathworks.com/matlabcentral/answers/368921-yyaxis-change-ylim-for-both-axes
Thank you very much for your inputs!!

You should set ylim() for each axes separately. For example:
x = linspace (0, 6, 51)';
y1 = sin (x);
y2 = cos (x);
yyaxis ('left');
plot (x,y1);
ylim ([-2,2]);
yyaxis ('right');
plot (x,y2);
ylim ([-6,6]);

Thanks!!!
So every time I need to modify the ylim manually so that it passes with the left side axis. Is it possible to do it automatically?

ylim() only affects the current axis. When the command yyaxis(AA,'right') is executed, all of the future commands (including ylim()) affect the right yyaxis. You have to do this manually because the scale of your data for the left yyaxis and the right yyaxis differs significantly. The left yyaxis and the right yyaxis are separate and the ruler scale in one side does not affect the one on the other side.
