Is it possible to set the default font size for shared axis labels in Tiled Layouts?

I tried the following code, but it does not affect the font size for shared titles and axis labels in TiledChartLayout objects.

set(groot,'defaultAxesFontSize',16);
t = tiledlayout(2,1);
t.XLabel.String = 'x-axis label';
t.YLabel.String = 'y-axis label';
t.Title.String = 'title';
nexttile();
plot(1:10);
nexttile();
plot(1:10);

I also tried to set default properties for Text objects because the XLabel and YLabel properties of TiledLayoutChart objects are Text objects,

set(groot,'defaultTextFontSizeMode','manual');
set(groot,'defaultTextFontSize',16);

but these 2 lines did not affect any of the text in the example figure shown above. I double-checked default values for groot and called

reset(groot);

to make sure that no other default property values defined by me could potentially conflict with the example code shown above.

Just additionally use

set(groot,'defaultAxesFontSizeMode','manual');

with the specification of the 'defaultTextFontSizeMode' to 'manual'. Then it maybe should work fine.

So maybe

myfontsize = 16;
set(groot,'defaultAxesFontSizeMode','manual')
set(groot,'defaultTextFontSizeMode','manual')
set(groot,'defaultAxesFontSize',myfontsize)
set(groot,'defaultTextFontSize',myfontsize)

should do the trick.

Use this instead:

set(gca, 'FontSize', 16.0);

I am running into the same problem, and nothing really works. I get default font and size

It works as suggested in my previous answer - see this example:

x=0:10;
y1 = 2*x.^2-5*x+3;
y2 = -2*x.^2+5*x-3;
subplot(211)
plot(x,y1, 'ro--', 'LineWidth', 2)
set(gca, 'FontSize', 16.0);
xlabel('x values')
ylabel('y_1(x)')
subplot(212)
plot(x, y2, 'bd-.', "LineWidth", 1)
set(gca, 'FontSize', 11.0);
xlabel('x values')
ylabel('y_2(x)')

It worked, but I had to update my Matlab version from 2022b to 2025, apparently it is a bug.

title(t,'KTO-dp4', 'FontName', 'Cambria', 'FontSize', 15);
xlabel(t,'Wavenumber (cm^{-1})', 'FontName', 'Cambria', 'FontSize', 15);
ylabel(t,'Absorbance', 'FontName', 'Cambria', 'FontSize', 15);
