How to increase text size for asterisk for significant data

I am using the function sigstar, which helps make significance bars for data. An example of the code is:

  R=randn(30,2);
  R(:,1)=R(:,1)+3;
  boxplot(R)
  set(gca,'XTick',1:2,'XTickLabel',{'A','B'})
  H=sigstar({{'A','B'}},0.01);
  ylim([-3,6.5])
  set(H,'color','r')
 

I want to increase the size of the asterisks that form on top of the bars. Does anyone know how to do this?

Attached above is an example of the bar graph I made.

I have tried the following code and here is the error:

  >> set(H,'color','r','LineWidth',1,'TextSize',12)
  

Error using set

Unrecognized property TextSize for class Line.

R=randn(30,2);
R(:,1)=R(:,1)+3;
boxplot(R)
set(gca,'XTick',1:2,'XTickLabel',{'A','B'})
H=sigstar({{'A','B'}},0.01);
ylim([-3,6.5])

Note, from the help comment at the top of sigstar:

    % Outputs
    % H - optionally return handles for significance highlights. Each row is a different
    %     highlight bar. The first column is the line. The second column is the text (stars).

Therefore, e.g.:

% set the line color and linewidth:
set(H(:,1),'color','r','LineWidth',1)

% set the text fontsize:
set(H(:,2),'FontSize',22)

Thank You! I just solved this problem using by changing the original function sigstar.m and changing it there but this works too thank you very much!

The correct parameter for matlab plots is 'FontSize'

yeah that didn't work either it gave the same error because I was calling the line. Thank you for helping!
