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

I found that "print" command can solve this problem.

fig = figure;
plot(x, f(x));
title('the smallest n = 1', 'FontSize', 24);
xlabel('x', 'FontSize', 24);
ylabel('x''', 'FontSize', 24);
print(fig, 'PicName', '-dpng');

The third argument is to specify the format. In my case, I would like to save it to png file.

The font size would remain the values I set now.
