Multiple ylabels for tiledlayout

Suppose I am drawing a 4*6 figure with tiledlayout. Now I want to let the first and the second rows of figures share the same ylabel, and so do the third and the fourth rows. I looked for solutions but found nothing useful. I tried to create two different tiledlayout on one figure, but it turns out that tiledlayout function does not allow this. Thus, is there any suggestions?

One approach would be to create a 2x1 tiledlayout where inside each tile you nest another tiledlayout of dimension 2x6. You can facilitate this by downloading nestedLayouts() from the File Exchange,

Example:

[ax,t,T]=nestedLayouts([2,1],[2,6]);

for i=1:numel(ax) %populate all 24 axes with plot data
 plot(ax(i),rand(1,5));
end

for i=1:numel(t)  %Give each outer tile its own ylabel
 ylabel(t(i),"ylabel No. "+i);
end

Thanks for your comment. I agree that this kind of nested tiledlayout is a good solution.

Hi! I found there is a problem: when we use old version MATLAB (I tried R2019b), this method will lead to the following error:

"

Error using tiledlayout

TiledChartLayout cannot be a child of TiledChartLayout.

The answer applies to the Matlab version that you posted with your question,

[Cunxin Huang]

Yes. But I wonder if there exists a solution for an older version like R2019b.

I haven't used it myself, but there is this FEX offering,

which has a "Pick of the Week" designation to vouch for it.
