How do I change the font size in my legend?

3.860 views (last 30 days)
When I attempt to change the font size of the text in a legend using the code shown below, the text becomes very large:
plot(rand(4))
AX=legend('One','Two','Three','Four');
LEG = findobj(AX,'type','text');
LEG.FontSize = 10;

You can change the font size for a MATLAB legend by setting the 'FontSize' property of the Legend object.
For example, plot four lines. Create a legend and assign the Legend object to the variable 'lgd'. Then, use dot notation to access the 'FontSize' property and set the value to 14 points.
plot(rand(4))
lgd = legend('One','Two','Three','Four');
lgd.FontSize = 14;
Alternatively, you can specify the 'FontSize' property using a name-value pair argument in the 'legend' command. When including name-value pair arguments, include the legend labels in a cell array. For example:
legend({'One','Two','Three','Four'},'FontSize',14)

I had the same problem, I am using version 2016b. The Legend box became bigger but the text rermains small.
What can I do?
edit: I needed to change manually, very frustrating. Unconvenient for such an expensive software.

Here you go :
h = legend('x','y','z');
set(h,'FontSize',12);

Hi I am using 2015b. "h= legend('x','y','z'); set(h,'FontSize',12); worked really well and it is good when we need the axes' labels in bigger sizes However it took a very long time to proceed for such two simple lines! please advise

You need to pass the path of the directory containing the data to EigenfaceCore . See the example.m file for example.
