How do I resize fonts of scope (xy axes labeling fonts, numbers on axes, etc) in MATLAB 2015a?

Use the 'FontSize' property of the current axes:

set(gca,'FontSize',20)

this change all of the text in the figure i need to change only the numbers as shown in the image on this quastion

[Star Strider]

It doesn’t when I run it. It only changes the sizes of the numbers on the axes, leaving the title and axis labels unchanged.

[Ben11]

Yep for me it works also; i.e. it does the same as @Star Strider. Please see my comment below. OF course I used dummy values for the ticks and titles font size, but you can resize the title after changing the ticks if you like.

[Ben11]

Example code:

clc
clear

x = 1:6*pi;

figure;

plot(x,sin(x));

title('This is sin(x) vs x');

set(gca,'FontSize',18);

outputs this:

What you can do if you want to change the size of the title is assigning it a handle and modify its "FontSize" property directly:

hTitle = title('This is sin(x) vs x');
set(hTitle,'FontSize',30)

Be sure to add the title before setting font size. If you change font size then add the title it will be in the font size you just set. Though you can change it again afterwards.

Thanks all, definitevely brief and working. Best.

If you search for 'tick labels' or something similar, in the file exchange there are numerous options that replace the tick labels locked into the axes font size with text objects that can be manipulated independently.

I can't vouch for any particular one as I have never used any of them though.
