How to 'un' bold titles for MATLAB figures?

Question

I'm trying to combine a few Matlab plots into one figure and therefore I'm wondering how I can create 'normal' tiles above my plots instead of the bold titles provided by Matlab. Below an example.

figure
plot((1:10).^2)
title({'First line';'Second line'})

Solution

Make use of the 'FontWeight' argument:

figure
plot((1:10).^2)
title({'First line';'Second line'},'FontWeight','Normal')

Note also that you can access the 'FontWeight' argument for all text objects in your figure in one go---in case you have, e.g., several subplots in your figure---using findall:

myFig = figure;
subplot(2,1,1)
plot((1:10).^2)
title('First plot')
subplot(2,1,2)
plot((1:10).^2)
title('Second plot')

% Set 'Normal' font weight in both titles above
set(findall(myFig, 'Type', 'Text'),'FontWeight', 'Normal')

As stated in the comments above; for a single figure title, you can make use make use of \rm as an alternative. Note however that \rm depends on the (default) choice of 'Interpreter' as 'tex', whereas the approach above is valid for all choices of interpreter (however with no effect for text objects using interpreter 'latex').
