Original question body retrieved from Google cache:
Hi, I encounter a strange plotting behaviour. I use the command:
sgtitle
to insert a title above my subplots. Using this command, some figures appear to plot the title in bold, while others show 'normal' text. I prefer the latter. Please see the figures below. It really looks like a bug to me. It is a minor issue, but i would like to get all titles in plain text instead of bold. How can i fix this?
set(0,'defaulttextinterpreter','latex');
%% Code for Bold plot: (unprefered)
subplot(1,2,2); hold on
sgtitle('Steady Aerodynamic Model');
for k=1:1:length(real_p)
plot(v(j),real_p(k),'.k','MarkerSize',6);
end
xlabel(' v [m/s]'); ylabel( 'real $${\sigma}$$');grid on; hold off
subplot(1,2,1); hold on
for l=1:1:length(imag_p)
plot(v(j),imag_p(l),'.k','MarkerSize',6);
end
xlabel(' v [m/s]'); ylabel( 'imag $${\omega}$$');grid on; ylim([0 50]);
hold off
%% code for 'normal plan text' plot (prefered:)
sgtitle({'Steady Aerodynamic Model Theodorsen'})
subplot(1,2,1); hold on
plot(v,imag(p_final),'.k')
xlabel(' v [m/s]'); ylabel( 'imag $${\omega}$$');grid on; ylim([0 50]);
subplot(1,2,2); hold on
plot(v,real(p_final),'.k')
xlabel(' v [m/s]'); ylabel( 'real $${\sigma}$$');grid on;
Bold:
Not bold (prefered):

Doesn't change anything. If i select 'bold' by that setting, the title appears even bolder than it already is.

Yes you’re right didn’t test it.
