Problem changing tick label font size

Hello!

I am trying to change the size of the tick labels in a plot in matlab using the following code:

ax = gca; 
ax.FontSize = 40;

This seems to work for most people on this forum, but when I try it, the font size in the tick labels in the figure does not change. However, when I enter

ax.FontSize

in the command window, it returns:

Can someone please explain to me why Matlab seems to store the change in font size, but the font size doesn't actually change in the figure? Thanks! I am using Matlab R2022a

What interpreter are you using?

@Adam Danz I believe I am using the default, which I think is tex? Not completely sure how to check the interpereter or change it for the axes tick labels

Can you give a minimal example of some code where this does not work as expected?

Is it the case that even this simplest possible version does not work for you, on a brand-new MATLAB session?

ax = gca; 
ax.FontSize = 40;

Perhaps you have a lingering set of axes around that ax is referring to, such that you are not manipulating the axes you think?

Also experiment with

FIG = get(groot, 'CurrentFigure');
AX = get(FIG, 'CurrentAxes');
set(AX, 'FontSize', 40)

We don't have enough information to troublehoot.

One possibility is that the fontsize is not being applied to the intended axes. This could happen if the axes are within a figure with HandeVisibility turned off (e.g. uifigures). In this case, gca will not return the axes within the figure.

To avoid this possibility, instead of relying on gca(), specify the axes handle,

fig = uifigure(); 
ax = uiaxes(fig);
ax.FontSize = 40;

If this does not solve the problem, providing more information may help.
