% The |text| function creates one text object for each text description.
% Thus, |t| contains two text objects. 
%
% Change the color and font size for the first text object using |t(1)|.
% Starting in R2014b, you can use dot notation to set properties. If you
% are using an earlier release, use the |set| function instead. 

t(1).Color = 'red';
t(1).FontSize = 14;
