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);

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);
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:
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:
