How can I change the font size of the axes of the current graph without creating new axes? For example, if we have this plot already, how can I change the font size?
x = rand(10,10);
y = rand(10,10);
plot(x,y)

To change the font size, set the FontSize property on the axes object after plotting. For example:
x = rand(10,10);
y = rand(10,10);
plot(x,y);
set(gca,FontSize,20)
Starting in R2022a, you can use the “fontsize” function to change the font size for any graphics object that has text associated with it. In this case, pass the axes object to the “fontsize” function followed by the desired font size in points. For example:
fontsize(gca,20)
You can also change the font name using the “fontname” function. The font you specify must be installed on your system. For example, change the font of the current axes to Courier:
fontname(gca,"Courier")

On my end, I had to specify the fontsize unit as shown here.

See attached demo to see how you can independently change a wide variety of things in your axes.

Attach your script and say what you want each y axis to look like (fontsize, color, tickmarks, or whatever).

Solved the issue; I was using ax=gca; for both 'yyaxis left' and 'yyaxis right'. Fix was to have ax1 for left yaxis and ax2 for right yaxis; as far as I can tell thats what fixed it anyway...
Thanks for the response.

There is one minor correction with one of the otptions proposed by @Mat Fig using fontsize() the unit has to be specified:
x = 1:5;
y = randi(5,1,5);
plot(x,y)
fontsize(gca, 15,'points') % 'pixels', 'centimeters', 'inches'
