change the font of a legend in matlab

You can change the font of a legend in MATLAB by accessing the Legend object within the plot and modifying its properties. Here's an example code snippet:

main.m
% Create a sample plot
plot([1,2,3],[4,5,6],'DisplayName','Line 1');
hold on;
plot([1,2,3],[6,5,4],'DisplayName','Line 2');

% Add legend
lgd = legend;
lgd.FontName = 'Arial'; % Set font name
lgd.FontSize = 12; % Set font size
227 chars
10 lines

In this example, the FontName property is used to specify the font of the legend text (in this case, Arial), and the FontSize property is used to specify the font size (in this case, 12). You can customize these properties further according to your preferences.
