Bug report: If given an array (not a vector) of objects, then linkprop doesn't link properties for all the objects it is given, but rather a subset of them:

fig=figure;

nrow=3;

ncol=2;

tl=tiledlayout(nrow,ncol);%,'tileindexing','columnmajor');

ax=gobjects(nrow,ncol);

for cnt1=1:nrow*ncol

ax(cnt1)=nexttile;

plot(1:2,3:4)

end

ln=linkprop(ax,{'xlim','ylim'});

ax(1).XLim=[1.5,2.5];

disp('ln.Targets(:).XLim')

ln.Targets(:).XLim

ans = 1x2

1.5000 2.5000

ans = 1x2

1.5000 2.5000

ans = 1x2

1.5000 2.5000

ans = 1x2

1 2

ans = 1x2

1 2

ans = 1x2

1 2

disp('ax(:).XLim')

ax(:).XLim

ans = 1x2

1.5000 2.5000

ans = 1x2

1.5000 2.5000

ans = 1x2

1 2

ans = 1x2

1.5000 2.5000

ans = 1x2

1 2

ans = 1x2

1 2

Which objects do get linked depends on whether 'rowmajor' or 'colummajor' tile indexing are used. It sort-of operates on just the first row/column of objects given in the array, for instance try changing nrow and ncol to be equal to each other. I have the problem in 2023a, seems it's also present in the latest release (2024a) based on the results above.

I submitted a bug report. Mathworks has verified this is a bug. Unclear if it'll get addressed, so I asked that they at least update the documentation to state the axes object array must be a vector.

Hi @T A,

I seems like there is some sort of a timing issue. Even i'm facing the similar issue. The messages to link the axes are arriving at the client before the messages to register the axes control for each axes, so it's not able to link whichever axes is created last, as its control is not yet created when the message to link it is received.

I would suggest to contact someone from the Mathworks Technical Support: https://www.mathworks.com/support/contact_us.html

I hope this helps.
