Change figure size based on the number of nexttile

I want to generate a figure of many imagesc using tiledlayout('flow'). How can I make my figure size adjust depending on the number of nexttile used in a loop? Is there any way I can set the size for each individual in tiledlayout? So that the figure appreance will not depend on the number of loop iteration.

I found some thing similar with what I am looking for here but I want to do it in a reserve way

Well, when you use the 'flow' option, that's what you've told tiledlayout you want -- the size/location of the figures to update dynamically when each nexttile call comes.

If you want a fixed layout, then use the tiledlayout(m,n) option where you define how many and the orientation a priori and then fill in the content when you get there.

There are some options to control the amount of whitespace between tiles to adapt the appearance but individual axes positions/sizes are not modifiable with the 'Position'properties of a normal axes object.

There is an ability to nest layouts to create nonuniformly-sized charts, see the properties documentation 'Layout' property for the details on that.

But, if you don't want the sizes changing dynamically, don't use 'flow'

thank you very much for your responses!

I have tried both "flow" and (m,n) but it does not seem to be a matter though. They all just try to fit in the default figure size. Have a look here. I use the space option with "tight". All of my figure are uniform size so I was thinking it should not be challenging.

I don't follow your problem -- if I follow the first example at tiledlayout which uses a 2x2 layout, I get the first axes in the first ULH corner and the second doesn't change the layout arrangement nor size, just goes into second tile (URH corner) and so on...

That also seems to work if change the creation of the tiledlayout to be

hTL=tiledlayout(2,2,'TileSpacing','compact','Padding','compact');
nexttile
surf(X,Y,Z)
nexttile
contour(X,Y,Z)
...

or if m,n are 7,2 instead...

hTL=tiledlayout(2,2,'TileSpacing','compact','Padding','compact');
nexttile
surf(X,Y,Z)
nexttile
contour(X,Y,Z)
nexttile
...

produces...

Isn't that precisely the effect you're looking for?

thank you very much for your time! Sorry I did not explain myself very well

So I want to create N subplots inside a single figure using tiledlayout. Because my N is vary, could be 2 could be 20, meanwhile the figure size is the same as matlab default or I can set its position like set(gcf,'Position',[a b c d]),...

My question is how I can relate N to the figure size, so when N is large, the figure will be adaptive to be bigger so each subplot can be seen easily.

I hope it makes more sense to you now.

Now while writing this, I just realize that I can set the figure position height and width depend on N actually :)

Thank you very much for your time again! Much appreciated

AHa! That, indeed, is a different problem. Yes, you can make the figure width/height a function of the m,n layout numbers. NB: you can retrieve the actual monitor pixel size from the groot stucture that can give you the limits of the current monitor that you could scale to.

I will look into groot that you mention, have never heard of it before. Thank you v much!!
