How to change the font size of a plot's title and axis labels and save it?

Question

Every time I save a plot picture as jpg or png, font size of title and axis label is changed back to default automatically. My code is like this:

figure
plot(x,          


        

Answer 1

Because it just applies for the current figure.

If you want to set the same font size for the whole session, use:

set(0,'defaultAxesFontSize', 12);

If you want that permanently, put it in your start-up file.

By the way, as you can see here you can build every "default property" you wish by concatenating default + class name + property.
