Issues with overlapping graphs in nested tiledlayouts

Hello,

I'm trying to plot a series of humidograms by the airmass source region (aka cluster) and season the data was collected in. The for loop below is to help plot each season (if there is data from both seasons, as some clusters only appeared in one season) of the data per cluster, and so I made a nested tiledlayout, with the inner tiledlayout for the seasons and the outer tiledlayout for the clusters. I was going to work on resizing everything after figuring out this present issue, which is that everytime I run it, it plots each graph over top of another empty graph (as you can see in the photo below). The empty graph doesn't have any data in it and so I'm not exactly sure why it's doing this. And so, I'd like to see if someone sees anything that might be causing this issue or has any links to resources that could help me identify the issue.

Thank you

Your code doesn't run, see error message above.

My apologise, I missed a variable. It should be in there now, thank you!

In

if 0        % so can execute later code
t_lrg = tiledlayout('flow','TileIndexing','rowmajor'); % outer layout
for i = 1:max(clsnum)
    nexttile(t_lrg)
    p_tbl_sum = mltm_dq_all{1,1}{i,1};
    p_tbl_win = mltm_dq_all{2,1}{i,1};
    if isempty(p_tbl_sum) % if only winter data
        t = tiledlayout(t_lrg,1,1); % inner layout
        nexttile(t)
        ...
    end
end
end

you create the outer tile and then a new tiledlayout object inside it...if there is only one, then the new one is the same size and overlays the t_lrg axes and so doesn't appear although it is behind the second just the same. If there are two, then they are smaller and so don't fully occlude the outer.

I am not quite sure the best way to produce the effect desired otomh, you might try simply setting 'Visible','off' for t_lrg; I'm not sure about t inheriting that and being invisible, too, or not. If so, then set the axes color to the background color to make it disappear.

I've not gotten terribly deep into just what one can do with tiledlayout whether it has a particular syntax for this or not; I'd study all the examples closely and see if there is anything that does something simliar to what you're wanting for ideas.

But, the above is where the outer axes is coming from; it's doing exacty what you told it to do... <lol>

It's easy enough to show what's happening...

t_lrg = tiledlayout('flow','TileIndexing','rowmajor');  % outer layout
nexttile(t_lrg)                                         % make active
t = tiledlayout(t_lrg,1,1);                             % inner layout inside t_lrg
nexttile(t)                                             % show it

figure
t_lrg = tiledlayout('flow','TileIndexing','rowmajor');  % outer layout
nexttile(t_lrg)                                         % make active
t = tiledlayout(t_lrg,2,1);                             % inner layout inside t_lrg
nexttile(t)                                             % show it

The above shows what was described above...let's spearmint about the visibility idea...

figure
t_lrg = tiledlayout('flow','TileIndexing','rowmajor');  % outer layout
h1=nexttile(t_lrg);                                     % make active
t = tiledlayout(t_lrg,2,1);                             % inner layout inside t_lrg
nexttile(t)                                             % show it
h1.Visible='off';

That does seem to fix the visibility issue; there's probably a better solution.

You still have an issue it appears of there being two axes even with the single inner axes, though. I didn't delve into that.

Answer 1

[Matt J]

Remove the line

nexttile(t_lrg)

It creates an axes in the outer layout.

Answer 2

[the cyclist]

I think you don't want the very first nexttile call, just after

for i = 1:max(clsnum)

which creates the "underneath" axes, that are not used. Removing that line, and running your code here.
